Class Information
Number: 257/56
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 > Responsive to nonelectrical external signals (e.g., light) > With impurity other than hydrogen to passivate dangling bonds (e.g., halide)
Description: Subject matter wherein the amorphous semiconductor material is doped with an impurity other than hydrogen (e.g., a halide) for providing electrical stability by completing chemical bonds between semiconductor atoms which were not completed due to the amorphous nature of the semiconductor active layer material.
