Mw. Dellow et al., TUNNELING HOT-ELECTRON TRANSISTOR AS A HIGH-POWER SOURCE AT TERAHERTZFREQUENCIES, Applied physics letters, 65(19), 1994, pp. 2463-2465
A novel device is proposed, based upon a tunneling hot electron transf
er amplifier, which exhibits the characteristics of negative different
ial resistance (NDR) coupled with high current gain. The mechanism whi
ch produces the NDR is known to be extremely fast. The combination of
these features suggests that such a device could be used as a high pow
er source of terahertz radiation. (C) 1994 American Institute of Physi
