摘要:

Propagation of pseudo surface modes, PSMs, propagating on SrF2epitaxial layers deposited on GaAs(111) was studied by means of Brillouin spectroscopy. A lowering of 3 ÷ 77% of the velocity values of the PSMs was detected in case of leaky modes of a relatively strong leakage. The observed deviations of the velocity of the PSMs are connected with the presence of a roughness region of fluoride/GaAs(111) interface extending on several nm.
