This chapter discusses some topics in the physics of metal-semiconductor junctions and metal-insulator-semiconductor (MIS) junctions. The former topic is treated first in a discussion of the metal-semiconductor junction band diagram at equilibrium and under an applied potential. The results are used ...
whereA⁎is the modified Richardson constant (containing the effective mass of the considered semiconductor). The effect of illuminating the metal-semiconductor junction is similar to the case of a p–n junction (with a thin highly doped zone), being the semiconductor as the light absorber, henc...

Again, it is exactly the high-quality MXene-GaN van der Waals metal-semiconductor junction that leads to the fine distinction of photocurrents in different light absorption regions. As a result, the responsivity distribution can be observed and the light absorption enhancement can be confirmed. To...
semiconductor/liquid junction, or by a buried rectifying junction4. The buried junction can be established by variations in doping (homojunction), offsets in the conduction and valence band levels at an interface (heterojunction), or by differences in Fermi level at a metal-semiconductor (MS) ...
Energy band diagram for metal–oxide–semiconductor. Applying a voltage to the gate electrode causes an electric field E between the both sides. This makes a displacement of carriers near each side forming a two space–charge region. When no charge is present at the interface between the oxide...
摘要: The schematic energy level diagram of a p-n junction made in graded-gap epitaxial CdxHg1−xTe layer is presented. This diagram explains the narrow photoresponse peak of the photovoltaic effect and its high quantum efficiency. DOI: 10.1002/pssa.2210400229 被引量: 5 年份: 1977 收藏...
