<P>Since the discovery of graphene, layered transition metal dichalcogenides (TMDs) have been considered promising materials for applications in various fields because of their fascinating structural features and physical properties. Doping in semiconducting TMDs is essential for their practical application. In this regard, two-dimensional (2D) Si materials have emerged as a key component of 2D electronic, optics, sensing, and spintronic devices because of their complementary metal-oxide-semiconductor (CMOS) compatibility, high-quality oxide formation, moderated bandgap, and well-established doping techniques. Here, we report the tuning of the electronic properties of Si nanosheets (NSs) using a plasma-doping technique. Using this doping process, we fabricated <I>p</I>-<I>n</I> homojunction diodes and transistors with Si NSs. The estimated high ON/OFF ratio of ∼10<SUP>6</SUP> and field-effect hole mobility of 329 cm<SUP>2</SUP> V<SUP>-1</SUP> s<SUP>-1</SUP> suggest a high crystal quality of the Si NSs. We also demonstrate vertically stacked heterostructured <I>p</I>-<I>n</I> junction diodes with MoS<SUB>2</SUB>, which exhibit rectifying properties and excellent light response.</P> [FIG OMISSION]</BR>

Background Non-functioning pituitary adenomas (NFPA) invading into the cavernous sinus are surgically challenging. To decrease recurrence rate, surgeon makes a strong endeavor to resect tumor gross totally. However, gross total resection (GTR) is difficult to achieve with cavernous sinus invasion. Recently, a new classification system for cavernous invasion of pituitary adenomas was suggested. The aim of this study is to validate this new classification system and to identify limitations and consid-erations in designing treatment strategies for patients with NFPA involving the cavernous sinus. Methods Between January 2000 and January 2012, 275 patients who underwent operation for NFPA were enrolled in the study. Median age was 50 years (15-79 years). There were 145 males and 130 females. The median follow-up duration was 4 years (range 1-12.5 years). Results Related to extent of tumor removal, GTR was obtained in 184 patients (66.9%), near total resection (NTR) was obtained in 45 patients (16.3%), and sub-total resection (STR) was obtained in 46 patients (16.7%) of a total 275 patients. There were statistically significant differences between the extent of resection and the new Knosp classification (p<0.001). In the high-grade group of the new Knosp classification, there was no difference in recurrence between patients who underwent GTR or NTR only and those who underwent STR with adjuvant radiation therapy (p=0.515). Conclusion In case of high risk of surgical complications, STR with adjuvant radiation therapy can be considered as an alternative strategy for safe treatment of cavernous-invading adenomas.
