Abstract: This thesis involves the study of the band structures of bulk wurtzite beryllium oxide (BeO). The band structures of bulk wurtzite BeO are calculated with the aid of computer simulation by utilizing the empirical pseudopotential method (EPM). The calculated band gap energy at the T point is in good agreement with various results obtained from the calculation of the band structures of BeO based on the local density approximation (LDA) method. Besides that, the eight parameters of the beryllium (Be) and oxygen (O) atom pseudopotential form factors with Schluter's formula are obtained. It is subsequently found that the ordering of the BeO at the top of the valence band is A (T7) - B(T9) - C(T7) due to a negative spin-orbit (SO) splitting.
