An accurate simulation study on capacitance-voltage characteristics of metal-oxide-semiconductor field-effect transistors in novel structures

Yu, E.,Cho, S.,Park, B.G. North-Holland 2017 PHYSICA B-CONDENSED MATTER - Vol.521 No.-

<P>An essential and important method for physical and electrical characterization of a metal-oxide-semiconductor (MOS) structure is the capacitance-voltage (C-V) measurement. Judging from the C-V characteristics of a MOS structure, we are allowed to predict the DC and AC behaviors of the field-effect transistor and extract a set of primary parameters. The MOS field-effect transistor (MOSFET) technology has evolved to enhance the gate controllability over the channel in order for effectively suppressing the short-channel effects (SCEs) unwantedly taking place as device scaling progresses. For the goal, numerous novel structures have been suggested for the advanced MOSFET devices. However, the C-V characteristics of such novel MOS structures have not been seldom studied in depth. In this work, we report the C-V characteristics of ultra-thin-body (UTB) MOSFETs on the bulk Si and silicon-on-insulator (SOI) substrates by rigorous technology computer-aided design (TCAD) simulation. For higher credibility and accuracy, quantum-mechanical models are activated and empirical material parameters are employed from the existing literature. The MOSFET structure and the material configurations are schemed referring advanced logic technology suggested by the most recent technology roadmap. The C-V characteristics of UTB MOSFETs having a floating body with extremely small volume are closely investigated.</P>

Yu, E.,Shim, J.S.,Kim, I.,Kim, J.,Han, S.H.,Kim, H.J.,Kim, K.H.,Yamaguchi, M. IEEE 2005 IEEE transactions on magnetics Vol.41 No.10

For improving high-frequency characteristics and soft magnetic properties of (Fe <TEX>$_7$</TEX> Co <TEX>$_3$</TEX> )B-based thin films, the effects of Ni addition and an oblique deposition method on the microstructures have been examined. The Ni addition to (Fe <TEX>$_7$</TEX> Co <TEX>$_3$</TEX> )B films was found to enhance B segregation on grain boundaries, which resulted in the formation of a well-defined columnar structure and the increase of film resistivity. Utilizing the columnar structure, large in-plane anisotropy was induced by an oblique deposition method which enabled the control of the inclination angle of the columns. As a result, the ferromagnetic resonance of (Fe <TEX>$_7$</TEX> Co <TEX>$_3$</TEX> ) <TEX>$_71$</TEX> Ni <TEX>$_7$</TEX> B <TEX>$_22$</TEX> thin films reached 6.2GHz.

The inflammatory reaction to tissue damage during surgery may induce central sensitization followed by hyperalgesia. Previous studies suggest that central sensitization is related to N-methyl-D-aspartate (NMDA) receptor activation, which can be blocked with NMDA antagonist, ketamine. Thus, we compared the effect of preoperative intravenous and epidural low doses of ketamine with placebo on serum interleukin-6 (IL-6) level and postoperative pain. ASA class I and II women scheduled for C-sections received intravenous ketamine 0.15mg/kg(group 2) or placebo(group 1), or epidural ketamine(0.15 mg/kg) before the operation. IL-6 levels were measured before and during the operation, and 8, 24, and 48 hrs after the operation. Visual Analogue Scales(VAS) and Verbal Ration Scales(VRS) were measured at 8, 24, and 48 hrs after the operation. Serum IL-6 levels at 8, 24, and 48 hrs after the operation were significantly lower in the intravenous ketamine and epidural ketamine groups than in the control group. VAS at 8 hrs and 48 hrs after the operation were significantly lower in the epidural ketamine group. VAS at 8 hrs and 48 hrs after the operation were significantly lower in the epidural ketamine group than in the control and intravenous ketamine groups. In conclusion, in the preoperative intravenous and epidural administration of low doses(0.15mg/kg) of ketamine, both are effective in reducing postoperative IL-6 levels. Epidural Ketamine is more effective than intravenous ketamine in postoperative pain control.

L-FUZZY UNIFORM SPACES

Yue, Yue-Li,Shi, Fu-Gui Korean Mathematical Society 2007 대한수학회지 Vol.44 No.6

The aim of this paper is to study L-fuzzy uniformizable spaces. A new kind of topological fuzzy remote neighborhood system is defined and used for investigating the relationship between L-fuzzy co-topology and L-fuzzy (quasi-)uniformity. It is showed that this fuzzy remote neighborhood system is different from that in [23] when $\mathcal{U}$ is an L-fuzzy quasi-uniformity and they will be coincident when $\mathcal{U}$ is an L-fuzzy uniformity. It is also showed that each L-fuzzy co-topological space is L-fuzzy quasi-uniformizable.

Research on the Impact of Perfect Diary Offline Experience Marketing on Consumer Behavior

Yue Wei(Yue Wei) 동북아경상학회 2022 동북아경상연구 Vol.3 No.2

Purpose - In recent years, with the rapid improvement of China’s economy, technology, and consumption level, the beauty industry gradually occupies an important part of the national economy, and the demand for consumers’ spiritual level is also higher and higher. Design/Methodology/Approach - This paper focuses on the developing beauty product market in the era of the experience economy, selects the most representative perfect diary brand as an, example and finds the marketing problems of offline experience store of perfect diary brand from the perspective of experience marketing. Findings - This paper uses experiential marketing in the offline experience store of the perfect diary brand as the research object. Using SPSS statistical analysis method and questionnaire survey method, this paper deeply analyzes the industry status of the offline experience store of perfect diary brand, makes assumptions on the relationship between experiential marketing and consumer perceived value of the offline experience store of perfect diary brand, and analyzes the relationship among experience marketing, perceived value, and consumer behavior. Research Implications - Based on the experimental results, this paper puts forward a series of marketing suggestions to improve the market competitiveness and popularity of the perfect diary offline experiestorestore, and obtains marketing strategies according to the actual situation.

이수지 경계 그림책 삼부작의 북 디자인 연구

숭열열 ( Yue-yue Chong ),정재완 ( Jae-wan Jeong ) 한국디자인트렌드학회 2019 한국디자인포럼 Vol.24 No.3

연구배경 최근 시대의 변화에 따라 그림책 작가들이 단순히 그림만 창작하지 않고 스토리와 그림, 디자인까지 창작하는 경우가 많다. 작가 이수지의 그림책 삼부작은 스토리와 삽화를 같이 창작하며 책의 구조까지 고려해서 창작한 그림책 이다. 본 연구는 이수지의 경계 삼부작의 북 디자인을 연구 하고자 하였다. 연구방법 우선 북 디자인을 이해하고 북 디자인의 요소와 그림책의 특징을 문헌 연구를 통해 고찰하였다. 그 후 그림책 북 디자인이론의 바탕으로 세 권의 그림책에 있는 각 북 디자인 표현요소를 분석하였고, 분석된 결과를 그림책 특성을 결합해서 정리하였다. 또한 주제에 적합한 그림책의 구조와 더 다양한 가능성을 도출하였다. 연구결과 각 그림책은 주제와 맞게 판형의 공통점으로 책의 제본 선을 이용해서 두 그림책 안에 세계를 나누어져 있었고 그림책 디자인 전체의 통일성이 있었다. 각 그림책 표지의 제목은 주제와 내용이 일치하게 표현되어 있었다. 연구결과 삼부작의 북 디자인은 그림책을 읽은 과정에서 충분한 상상력과 감정을 느낄 수 있도록 구성되어 있었다. 결론 그림책의 판형과 펴는 방식은 주제에 맞게 실제 물체나 공간 따라 비슷하게 만들어 취미와 독특성이 살릴 수 있다. 책 자체의 구조를 이용해서 책의 외적 구조부터 내부구조까지 하나의 공간이 될 수 있다. 제본 선의 이용일 뿐만 아니라 책의 변과 각을 디자인을 통해 이용하면 책의 독특성과 더 다양한 상상력을 만들 수 있다. Background According to the development of the age, picture book writers do not create simple pictures but often create stories, pictures, and designs. Lee Suzy ‘s trilogy of boundary picture books created by considering the structure of the book and creating the story and the submission together. This study aims to study Lee Suzy ‘s trilogy of boundary picture book‘s book design. Methods First , research the elements of book design and the features of picture book through literary by understanding book design. Based on picture book design theory, analyze each book design expression element in three picture books. Based on the analysis results, the structure and various possibilities of the picture book are summarized. Result Each picture book has a book shape that matches the theme. Use the middle line of the picture book to express reality and fantasy. The cover of each picture book is consistent with the theme and content. The unique book design of the trilogy makes the reading process of this book sufficiently imaginative and interesting. Conclusion The layout of the picture book, the page turning method can be based on the physical object, consistent with the theme. Using the structure of the book itself, make the book a whole from the external structure to the internal structure. Not only the use of the centerline of the book, but also the rational use of the side and angle of the book can make the book unique and more imaginative.
