          김원종,홍진웅,Kim, Weon-Jong,Hong, Jin-Woong 한국전기전자재료학회 2009 전기전자재료학회논문지 Vol.22 No.11

          In a triple-layered structure of ITO/N,N'-diph enyl-N,N'bis(3-methylphenyl)-1,1' - biphenyl-4,4'-diamine(TPD)/tris(8-hydroxyquinoline)aluminum($Alq_3$)/(2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline(BCP)/Al device, we have studied the electrical and optical characteristics of organic light-emitting diodes(OLEDs) depending on the deposition condition of BCP layer. Several different sizes of holes on boat and several different deposition rates were employed in evaporating the organic materials. And then, electrical properties of the organic light-emitting diodes were measured and the performance of the devices was analyzed. It was found that the hole-size of crucible boat and the evaporation rate affect on the surface roughness of BCP layer as well as the performance of the device. When the hole-size of crucible boat and the deposition rate of BCP are 1.2 mm and $1.0\;{\AA}/s$, respectively, average surface roughness of BCP layer is lower and the efficiency of the device is higher than the ones made with other conditions. From the analysis of current density-luminance-voltage characteristics of a triple layered device, we divided the conductive mechanism by four region according to applied voltage. So we have obtained a coefficient of ${\beta}_{ST}$ in schottky region is $3.85{\times}10^{-24}$, a coefficient of ${\beta}_{PF}$ in Poole-Frenkel region is $7.35{\times}10^{-24}$, and a potential barrier of ${\phi}_{FN}$ in Fower-Nordheim region is 0.39 eV.

        • RF 스퍼터링법에 의한 SCT박막의 전기적 특성

          김원종,정의남,심상흥,박하용 三陟大學校 2001 論文集 Vol.34 No.1

          In this study, The (Sr1-xCax)TiO3(SCT) thin films are deposited on Pt-coated electrode (Pt/TiN/SiO2/Si) using RF magnetron sputtering method with substitutional contents of Ca at various substrate temperature. The structural properties of SCT thin films are analyzed using SEM, XRD, and EDS, and the electrical properties are studied by measuring the dielectric properties and the electrical properties are studied by measuring the dielectric properties and electrical conduction. The experimental results of electrical properties are summarized as follow. The dielectric constant is increased with increasing the substitutional contents of Ca, while it is decreased if the substitutional contents Ca exceeded over 15[mol%]. The maximum dielectric constant of thin film is obtained by annealing at 600[℃]. The dielectric constant changes almost linearly in temperature ranges of -80~+90[℃]. The temperature properties of the dielectric loss have a stable value within 0.1 independent of the substitutional contents of Ca. The capacitance characteristics had a stable value within ±5[℃]. The drastic decrease of dielectric constant and increase of dielectric loss in SCT thin films is observed above 200[㎑]. All SCT thin films used in this study show the phenomena of dielectric relaxation with the increase of the increase of frequency. Ⅴ-Ⅰ characteristics of SCT thin films show the increasing leakage current with the increases of deposition temperature.

          모드중첩법을 이용한 전단보 모델의 비선형 해석

          김원종,홍성목 한국지진공학회 1999 한국지진공학회논문집 Vol.3 No.2

          시간영역에서의 구조물의 해석은 직접적분법과 모드중첩법에 의하여 구해질 수 있다 그 중에서도 모드중첩법에 의한 해석방법은 몇가지 저차 진동모드를 사용하여 비교적 정확한 해를 구할 수 있기 때문에 동적해석에 널리 사용되고 있다, 그러나 비선형해석에서는 각 부재들의 상태에 따라 강성이 달라지므로 고유 진동모드를 정의할수 없거나 변화되는 강성에 따라 고유진동 모드를 지속적으로 다시 구하여야 하는 불편 있으므로 모드 중첩법을 이용한 비선형해석은 완전탄소성모델 등 극히 제한된 조건에서만 실행이 가능하였다 본논문에서는 강성행렬을 각 부재별로 분리시키고 비선형복원력과 초기선형복언력과 초기선형복원력의 차이를 하중항에 반영시킴으로써 모드중첩법을 이용하여 비선형 해석은완전탄소성모델 등 극히 제한된 조건에서만 실행이 가능하였다 본 논문에서는 강성행렬을 각 부재별로 분리시키고 비선형 복원력과 초기선형복원력의 차이를 하중항에 반영시킴으로써 모드중첩법을 이용하여 비선형해석이 가능한 방법을 제시하고자 한다. 특히 각 부재 강성을 각 부재의 상대변위의 함수로 나타냄으로써 연속적인 계산이 가능하게 하였다 본 논문에서 제시된 방법은 전단보모델에 적용하였으며 모드 개수를 변화시켜 지진하중에 의한 최대변위를 계산하여 이를 직접적분버에 의한 결과와 비교하였다. To analyze the dynamic behavior of structure, direct integration and mode superposition may be utilized in time domain analysis. As finite number of frequencies can give relatively exact solutions, mode superposition is preferable in analyzing structural behavior. In non-linear analysis, however, mode superposition is seldom used since time-varying element stiffness changes stiffness matrix, and the change of stiffness matrix leads to the change of essential constants - natural frequencies and mode shapes. In spite of these difficulties, there are some attempts to adopt mode superposition because of low cost compared to direct integration, but the result is not satisfactory. In this paper, a method using mode superposition in non-linear analysis is presented by separating local element stiffness from global stiffness matrix with the difference between linear and non-linear restoring forces to the external force vectors included. Moreover, the hysteresis model changing with the relative deformation in each floor makes it possible to analyze non-linear behavior of structure. The proposed algorithm is applied to shear beam model and the maximum displacement is compared with the result using direct integration method.

          Crucible Boat 홀 크기와 정공 수송층 증착속도에 따른 유기밭광 다이오드의 전기적 특성

          김원종,신현택,신종열,홍진웅,Kim, Weon-Jong,Shin, Hyun-Teak,Shin, Jong-Yeol,Hong, Jin-Woong 한국전기전자재료학회 2009 전기전자재료학회논문지 Vol.22 No.1

          In the structure of ITO/N,N'-diphenyl-N,N' bis (3-methylphenyl)-1,1'-biphenyl-4,4'-diamine(TPD)/tris (8-hydroxyquinoline)aluminum($Alq_3$)/Al device, we studied the efficiency improvement of organic light-emitting diodes due to variation of deposition rate of hole transport layer (TPD) materials using hole-size of crucible boat. The thickness of TPD and $Alq_3$ was manufactured 40 nm, 60 nm, respectively under a base pressure of $5{\times}10^{-6}$ Torr using a thermal evaporation. The $Alq_3$ used for an electron-transport and emissive layer were evaporated to be at a deposition rate of $2.5\;{\AA}/s$. When the deposition rate of TPD increased from 1.5 to $3.0\;{\AA}/s$, we studied the efficiency improvement of TPD using the hole-size of crucible is 1.0 mm. When the deposition rate of TPD is $2.5\;{\AA}/s$, we found that the average roughness is rather smoother, the luminous efficiency the external quantum efficiency is superior to the others. Compared to the two from the devices made with the deposition rate of TPD is $2.0\;{\AA}/s$ and $3.0\;{\AA}/s$, the external quantum efficiency was improved by four-times and two-times, respectively.

          김원종 한국인터넷전자상거래학회 2019 인터넷전자상거래연구 Vol.19 No.2

          Luxury brands have generally been consumed by the well-to-do group among society. Nonetheless, from the mid 21st century, luxury item markets have been extended to customer groups with middle-class and lower-class earnings. In this perspective, this research attempts to identify Korean consumers behaviors in the context of luxury vehicle market, by confirming effects of country-of-origin images on consumers’ purchase intention, mediating brand prestige, brand credibility, and perceived quality. Furthermore, the dimensions of country-of-origin image in this study has been divided into three dimensions of functional country-of-origin, social country-of-origin, and dynamic country-of-origin. For the purpose of empirical study, a survey has been conducted to Korean consumers focusing on the effects of country-of-origin image on purchase intention by selecting the brand of Mercedes-Benz manufactured by Germany. A total of 324 questionnaires have been used for final analysis. By utilizing SPSS 22.0 and AMOS 18.0, the results of structural equation model have confirmed the positive effects of functional country-of-origin effects on brand prestige and brand credibility, while the other components of country-of-origin image have not shown significant effects on brand prestige and brand credibility. In addition, the effect of brand prestige on brand credibility has been significantly associated, and the relationship of brand prestige and brand credibility with perceived quality have also been turned out to be positively linked. Lastly, the effects of brand prestige, brand credibility, and perceived quality on purchase intention have been shown to be positively associated.
