摘要：

Optical and electrical properties of the gallium telluride Ga2Te3 are reported. Lattice modes are investigated using far-infrared spectroscopy and polarized Raman scattering experiments. The far-infrared reflectivity spectrum which is analyzed using a Lorentzian-oscillator model and the Raman spectrum shows that this compound has a defect structure with disordered vacancies. Modes with A-symmetry are observed at 86 and 112 cm(-1). The semiconducting character is evidenced by electrical studies and the sensitive behavior to normal atmosphere is observed in the electrical conductivity of a sample maintained in air.
