Abstract

The quaternary alloy In_xGa_1-xAs_ySb_1-y highly doped with tellurium was grown on substrates of p-type GaSb in the direction (100) by liquid phase epitaxy (LPE). The longitudinal (LO) and transverse (TO) optical modes were obtained using the modified random-element iso-displacement model (MREI model). The comparison of the experimental results with obtained by the MREI model allows to confirm that the bands correspond to the modes associated LO and TO of the binary compounds GaAs and (GaSb + InAs).
