Abstract

1533191 Semiconductor transducers GOSUDAR N-I I PROEKT INST REDKOMETALLICHE PROMYSHLENNOSTI GIREDMET 30 March 1977 13464/77 Heading H1K A pressure sensitive semiconductor device comprises two sets of superposed layers of semiconductor material of the type AB 1-x C x formed from two materials, one having a direct and the other an indirect forbidden conduction band, the mean value of x for the two sets of layers being different, and A being a III or V element and B and C being V or III elements. In the examples described, direct forbidden band materials are GaAs and InP, and indirect forbidden band materials are GaP and AlAs. The resulting semiconductor layer material may be GaAs 1-x P x , AsGa 1-x Al x and InP 1-x Ga x . The value of x across the layer thickness may be constant or sinusoidally varying.
