B. Lambert et al., FEASIBILITY OF 1.5 MU-M STAIRCASE SOLID-STATE PHOTOMULTIPLIERS IN THEALGASB GAINASSB SYSTEM/, Semiconductor science and technology, 11(2), 1996, pp. 226-230
We report the growth of a staircase solid state photomultiplier struct
ure. The device is obtained by a combination of ternary AlGaSb and qua
ternary GalnAsSb graded layers epitaxied on GaSb substrates, using mol
ecular beam epitaxy. The different layers used in the structures have
been individually optimized for their electrical and optical quality.
A multiplication coefficient of 7, without excess noise, is estimated
on a six-step device, for a maximum voltage of only 15 V.
