The main objective of this chapter is to describe the mechanisms of recovery from radiation damage, which operate during irradiation but are usually obscured by the concurrent process of defect creation. Accordingly, the conventional rate theory is modified with account of radiation-induced Schottky ...
. Although micropipes have been largely eliminated in commercial wafers, other defects, such as stacking faults andpoint defectcomplexes, are responsible for inhomogeneities in SiC Schottky diodes (Skrommeet al., 2000; Tumakhaet al., 2005). These inhomogeneities are associated with a knee in the...
Chapter Junctions and Barriers 2 Schottky Barriers 2.1 Barrier Height, Interface States, Junction Formation, and Equilibrium Properties A Schottky barrier is similar to a pn junction or heterojunction in which the doping on one side increases to the point where it becomes metallic. The band diagram...
Liu and Lau reviewed the scattered results reported and suggested the nonideal Schottky contact behavior probably stemmed from surface defect which can cause inhomogeneity in the transport current even within a single device, while material quality and metal-GaN reactions were the other two contributing...
Answer to: Explain how the electrical conductivity of a crystal is affected by the Schottky and Frenkel defect. By signing up, you'll get thousands...
The similarity in the pinning position on a given semiconductor produced by both metals and oxygen suggests that the states responsible for the pinning resulted from interaction between the adatoms and the semiconductor. Support for formation of defect levels in the semiconductor at or near the ...
Regrown modulation-doped 2DEG heterostructure layers are realized with an overall good surface morphology and a low surface defect density. Using a GaAs buffer layer the optical and electrical transport properties of regrown 2DEG layers are nearly the same as on conventionally grown samples. The ...
