Ya. Goldberg et al., A comparison of the temperature dependences of photoeffect quantum efficiencies in GaAs p-n structures and Schottky diodes, SEMICONDUCT, 33(7), 1999, pp. 804-806
A comparison is made of how the quantum efficiencies for photoelectric conv
ersion in p-n- and m-s-structures based on GaAs depend on temperature. For
photon energies less than or the same order as the width of the band gap, t
he temperature dependences of the p-n- and m-s- structures are similar. In
the range of photon energies larger than the width of the band gap, the qua
ntum efficiency of p-n- structures is temperature independent, whereas the
quantum efficiency of m-s- structures exhibits a strong temperature depende
nce. A qualitative explanation of this phenomenon is given. (C) 1999 Americ
