An analysis of the distributions of electronic states associated with hydrogenated amorphous silicon
Saad?M.?Malik Stephen?K.?O’LearyEmail author 《Journal of Materials Science: Materials in Electronics》2005,16(3):177-181
We study the distributions of conduction band and valence band electronic states associated with hydrogenated amorphous silicon. We find that there are substantial deviations from square-root distributions of electronic states, particularly deep within the bands and within the gap region. We clearly identify where these distributions of electronic states exhibit square-root functional dependencies by fitting square-root functional forms to some experimental data. The corresponding DOS effective masses are determined, and are found to be about 2 to 4 times greater than the crystalline silicon case. 相似文献

Oxyphilic cell (Hürthle cell) carcinomas of the thyroid gland, variant of follicular carcinoma, are more malignant than follicular non oxyphilic cell carcinomas with a similar size and degree of invasiveness. Gross features, microscopic features of oxyphilic, clear and bicolored cells carcinomas and diagnostic techniques are related with a differential diagnosis with papillary oxyphilic cell carcinoma. 相似文献

In this tutorial, we provided a comprehensive overview of coalitional game theory, and its usage in wireless and communication networks. For this purpose, we introduced a novel classification of coalitional games by grouping the sparse literature into three distinct classes of games: canonical coalitional games, coalition formation games, and coalitional graph games. For each class, we explained in details the fundamental properties, discussed the main solution concepts, and provided an in-depth analysis of the methodologies and approaches for using these games in both game theory and communication applications. The presented applications have been carefully selected from a broad range of areas spanning a diverse number of research problems. The tutorial also sheds light on future opportunities for using the strong analytical tool of coalitional games in a number of applications. In a nutshell, this article fills a void in existing communications literature, by providing a novel tutorial on applying coalitional game theory in communication networks through comprehensive theory and technical details as well as through practical examples drawn from both game theory and communication application. 相似文献

This study compared the performance of a glass ionomer (GC Gold Label 1, GIC) as a fiber post cementation system for glass fiber posts with a self‐adhesive resin cement (Relyx U200, RUC) and a conventional resin cement system (Scotchbond Muli‐Purpose and Relyx ARC, RAC). Thirty endodontically treated canines were randomly divided in three groups (n = 10), according to the fiber post cementation system: (RAC)—Scotchbond Multi‐Purpose and Relyx X ARC; (RUC)—Relyx U200 and (GIC)—GC Gold Label 1 Luting & Lining. Rhodamine was incorporated into the cementation system prior to the fiber post cementation. After glass fiber post cementation, roots were incubated in artificial saliva for 6 months. After that, specimens from the cervical, middle, and apical thirds of the post space were prepared and analyzed using a push‐out bond strength test and confocal laser microscopy. ANOVA one way and Tukey tests showed that GIC and RUC demonstrated similar push‐out bond strength values, independently of the post space third (p > .05); however, values were greater than those shown by RAC (p < .05). For dentin penetrability, GIC and RUC also had similar results (p > 0.05) and lower than RAC (p < 0.05). Inside the root canal, the cementation system using glass ionomer cement (GC Gold Label 1 Luting & Lining) has similar push‐out bond strength to the self‐adhesive resin cement (Relyx U200) and these were higher than the conventional resin (Relyx ARC), despite its higher dentin penetrability. 相似文献
