Single longitudinal‐mode optical phonon scattering in Ga0. 47In0. 53As
TP Pearsall, R Carles, JC Portal - Applied Physics Letters, 1983 - pubs.aip.org
We show that only one of the four Raman active modes in Gao. 47 Ino. 53 As shows the
required symmetry behavior for longitudinal optical (LO) phonons. An additional mode
previously supposed to be LO shows mixed-mode behavior and may be disorder activated.
Our results prove that only one phonon mode in Gao. 47 Ino. 53 As is active in scattering
electronic carriers, and thus in determining both electron and hole mobilities.
