Abstract : This report is presented in two main sections. Section II describes some successful experimental work which removed discrepancies between de Haas-van Alphen and galvanomagnetic measurements on Bi2Te3 and indicates the existence of a higher lying conduction band minima. Work on Bi2Se3 indicates the almost spherical nature of the six valley conduction band. In section III, a calculation of the electron and hole spectra of Bi2Te3 via the empirical pseudopotential method, is given. This calculation, done with the only amenable method for such a complex compound was successful in predicting the correct number of valence and conduction band extremes as well as showing the need for careful inclusion of the spin-orbit terms.
