Class Information
Number: 257/52
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
Description: Subject matter wherein the non-single crystal semiconductor material is amorphous, i.e., non-crystalline in the sense that (1) there is either complete disorder in the arrangement of atoms or molecules of the material or (2) there is an absence of any long range structural order that is detectable by electron or X-ray diffraction patterns of the material.
