Abstract
Hot-electron transistors (HETs) using an InGaAs/InAlGaAs heterostructure have been fabricated for the first time. The base layer thickness (base width) was 1000 Ã…,500 Ã… or 250 Ã…. The common-emitter current gain was measured at about 15 at 77 K for the 250 Ã… base HETs, which is, to the authors´ knowledge, the highest value ever reported.
