Abstract
Propagation of pseudo surface modes, PSMs, propagating on SrF2 epitaxi al layers deposited on GaAs(111) was studied by means of Brillouin spe ctroscopy. A lowering of 3 divided by 77% of the velocity values of th e PSMs was detected in case of leaky modes of a relatively strong leak age. The observed deviations of the velocity of the PSMs are connected with the presence of a roughness region of fluoride/GaAs(111) interfa ce extending on several nm.
