A three-terminal device is provided in which the "collector" current is determined by inducing an electron current of hot carriers such that these carriers are able to flow over an energy barrier and into an external circuit. The device is pictured in Fig. 1. The electrodes are labeled source (S), accelerator (A) and collector (C). The channel layer 2 is enclosed on both sides by epitaxial layers 1 and 3 having higher bandgaps than 2. The donor dopants in layer 1 and, to a lesser extent, layer 3, provide the carriers in layer 2 by the conductivity modulation effect. Layers 1 and 3 confine the unheated electrons to layer 2.
