Class Information
Number: 257/451
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Responsive to non-electrical signal (e.g., chemical, stress, light, or magnetic field sensors) > Electromagnetic or particle radiation > Light > Schottky barrier (e.g., a transparent schottky metallic layer or a schottky barrier containing at least one of indium or tin (e.g., sno 2 , indium tin oxide)) > Responsive to light having lower energy (i.e., longer wavelength) than forbidden band gap energy of semiconductor (e.g., by excitation of carriers from metal into semiconductor)
Description: Subject matter wherein the device responds to light having lower energy than the energy difference between the bottom of the conduction band and the top of the valance band of the semiconductor material that forms a junction with the metal.
