Formed at the boundary between an N-type and P-type semiconductor is a P-N Junction which is created by doping a single crystal of semiconductor. The nature of the P-N junction is one of the crucial ...
This course presents in-depth discussion and analysis of pn junction and metal-semiconductor contacts including equilibrium behavior, current and capacitance responses under bias, breakdown, ...
Photovoltaic effect in few-layer black phosphorus PN junctions defined by local electrostatic gating
In the past few years, the research effort on 2D materials has rapidly increased, driven by the great variety of layered materials and their exceptional properties when reduced to a few atomic layers ...
In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline ...
The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the “atomic level manufacturing” of semiconductors. The basic idea of ...
a, Schematic illustration of the buried channel transistor structure. b, THz emission from the PN junction. Ultrafast photocarrier transport due to the built-in electric field (drift current) ...
An organic solar cell is light, flexible, low cost and green device, hence regarded as a potential seed of innovation in renewable energy industry. The efficiency of energy conversion of the organic ...
