Class Information
Number: 257/450
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)) > With doping profile to adjust barrier height
Description: Subject matter wherein the height of the Schottky barrier is changed by varying the concentration of the impurity dopant in the semiconductor portion of the active junction region of the device.
