Sixteen micrometer Infrared Hot Electron Transistor

ABSTRACT. We have demonstrated a bound to continuum state GaAs/Al(x)Ga(1-x)As infrared hot electron transistor which has a peak response at lambda(sub p) = 16.3 micrometers. An excellent photo-current transfer ratio of alpha(sub p) = 0.12 and very low dark current transfer ratio of alpha(sub d) = 7.2 x 10(exp 5) is achieved at a temperature of T = 60 K.
