Abstract
A review of experimental results on microwave hot-electron noise specific to two-dimensional electron gas channels is given. Variation of electric field strength, heterobarrier height, doping and electron density, channel length, lattice temperature, microwave frequency have been used to excite/quench hot-electron velocity fluctuations of different origin. The noise sources specific to zero-heterojunction (planar-doped), single-, double- and triple-heterojunction channels are analyzed in terms of fast intrawell and interwell kinetic processes.
