Electric lead element - having laminar metal-insulator-semiconductor structure

摘要

Electric lead element, esp. suitable for electronically turntable retarding guide, have the form of a laminate; a metal strip is placed on an insulator (SiO2, Si3N4 or Al2O3) positioned on top of a semiconductor, the width of the metal strip is smaller than that of the insulator layer and the semiconductor layer. An electric contact can be formed on the semiconductor. The device is esp. suitable for waves having relatively low phase velocity and damping (frequency range from 100 MHz to a few GHz).
