R. Parker [5] has done much to reveal the nature of the silica surface. Three positions are recognized: isolated, vicinal and geminal, modeled in Figure 1.6. A vicinal grouping refers to adjacent silanols (-SiOH), hydrogen bonded. Geminal refers to two -OH groups attached to one silicon....

After preparing a number of silanes 47, Bienz and coworkers concluded that the most promising of them was compound 47a. This silane was prepared in three steps from triflate 49. Substitution of the silicon-bound hydrogen by chlorine, followed by reaction with 1-(ethoxy)vinyl lithium yielded an...

This paper describes the trends in the electronic structure of diamond, silicon carbide, the group-Ill nitrides and some related materials. The relationships between the electronic band structures in the zincblende and wurtzite structures are adressed. For SiC, the discussion is extended to other po...

The term “hot carrier injection” usually refers to the effect inMOSFETs, where a carrier is injected from the conducting channel in thesiliconsubstrate to thegate dielectric, which usually is made ofsilicon dioxide(SiO2). To become “hot” and enter theconduction bandof SiO2, an electron must...
