Analysis of amorphous-silicon devices

In recent years, Amorphous-Silicon devices have found interesting applications in large-area devices, such as the driving circuitry for flat-panel displays, scanner and print arrays, or chemical sensors. For this reason, many investigations have been carried out for the purpose of improving their performance, especially as far as stability and speed are concerned. To describe their electrical characteristics, analytical models or ad hoc numerical analyses have been proposed elsewhere. In this paper, the implementation of the model for amorphous silicon within the general-purpose simulator HFIELDS is shown, along with an application to a realistic case
