Class Information
Number: 257/57
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Non-single crystal, or recrystallized, semiconductor material forms part of active junction (including field-induced active junction) > Amorphous semiconductor material > Field effect device in amorphous semiconductor material
Description: Subject matter wherein the amorphous semiconductor active junction is a field effect device, i.e., one which has a conducting channel and two or more electrodes, one of which is denoted a source and the other a drain electrode, and in which the current through the conducting channel is controlled by an electric field coming from a voltage which is applied between the gate and source terminals thereof.
