Raman Scattering of Spontaneously Ordered Ga_(0.5) In_(0.5)P Alloy |
| |
| Abstract: | Abstract Raman scattering has been measured for three spontaneously or-dered and a disordered Ga_(0.5)In_(0.5)P alloy. The ordered samples have the charac-teristic band－gap energy anomaly（40， 90 and 120 meV lower than that of the disordered allov）． Three peaks have been observed in the Raman spectra， cor-responding to the Gap－like LO（～380 cm~(-1)）， InPlike LO （～360 cm~(-1)）and TO／～330 cm~(-1) ） modes， respectively. The Gap-like LO mode frequencies are 3 cm~f(-1)，6cm~(-1)， and 6 cm~(-1) larger than that of disordered sample for three ordered sample. The polarization properties of the ordered alloys is similar to that of the bulk Ⅲ-Ⅴ semiconductors. |
