Monte Carlo simulation of charge transport in amorphous selenium photoconductors
The electronic properties of amorphous materials are greatly affected by the density of localized states in the mobility gap of these materials. The exact shape of the density of states (DOS) distribution in amorphous ...
Excess Noise in Amorphous Selenium Used in X-ray Detectors
Amorphous selenium based digital radiography has attracted much attention because of selenium's high X-ray absorption and excellent charge transport properties, and the ability to be created thick (typically 100 to 1000 ...
X-ray Induced Effects and Charge Collection Efficiency in Stabilized Amorphous Selenium Based X-ray Photoconductors
Stabilized amorphous selenium (a-Se) photoconductive layers are currently used in most modern flat panel digital x-ray image detectors for mammography. The performance of these detectors depends, in part, on the electronic ...
Preparation & Characterization of n-Type Amorphous Selenium Films as Blocking Layers in a-Se X-ray Detectors
The "n-like layer" is important in multilayer layer amorphous selenium (a-Se) based Xray detector structures because it blocks the injection of holes from the positive electrode. The dark current in these devices is ...
