Abstract : These data sheets present a compilation of a wide range of electronic properties for the bismuth telluride-bismuth selenide system. Electrical properties include conductivity, dielectric constant, Hall coefficient, and mobility. Emission data were broken down into the varied electron and photon emissions which result from application of electromagnetic energy over a wide spectrum. Energy data include energy bands, energy gap, and energy levels, as well as effective mass tables, and work function. The optical properties include absorption, reflection, and the refractive index. Other magnetic data and irradiation effects are presented, as well as several related physical phenomena, such as piezoelectric properties, Debye temperature and electronic specific heat. Thermoelectric properties, thermal conductivity and figure of merit tables and graphs are presented. Each property is compiled over the widest possible range of parameters including bulk and film form, from references obtained in a thorough literature search. A summary of crystal structure and phase transitions is included. (Author)
