Title: Electromagnetic wave amplifier using two-stream instability
Inventor: IDESHITA TOMOSHI
IPC: H01L29/205
Filed: 1994-11-14
Abstract: PURPOSE: To generate electromagnetic waves from a two-stream part by a method wherein the two-stream part having an electron layer and a hole layer is provided and kinetic energy of electrons is converted into wave energy generated by mutual operations between electron plasma and hole plasma. CONSTITUTION: An InAs layer 13 works as a two-dimensional electron layer 21, a GaSb layer 14 works as a two-dimensional hole layer 23, and an AlSb layer 11 works as a partition layer 22 against electrons and holes. The two-dimensional electron and hole systems spacially separated by the AlSb layer can be realized. An electric field is applied to a direction parallel to the layers, whereby two-stream instability occurs and electromagnetic waves generate. If materials are decided, frequency characteristics of the two-stream instability are decided by coupling strength of the electron layer 21 and the hole layer 23. As parameters giving influences on the coupling strength, there are carrier concentration in a conductive layer, a distance between the electron layer 21 and the hole layer 23 and a diffusion time interval of carries.  Accordingly, it is controlled by doping or a layer thickness to obtain an optimum value.
