英文摘要	The energy bands of zinc-blende and wurtzite gan are calculated with the empirical pseudopotential method, and the pseudopotential parameters for ga and n atoms are-given. the calculated energy bands are in agreement with those obtained by the ab initio method. the effective-mass theory for the semiconductors of wurtzite structure is established, and the effective-mass parameters of gan for both structures are given the binding energies of acceptor states are calculated by solving strictly the effective-mass equations. the binding energies of donor and acceptor are 24 and 142 mev for the zinc-blende structure, 20 and 131, and 97 mev for the wurtzite structure, respectively, which are consistent with recent experimental results. it is proposed that there are two kinds of acceptor in wurtzite gan. one kind is the general acceptor such as c, which substitutes n, which satisfies the effective-mass theory. the other kind of acceptor includes mg, zn, cd, etc., the binding energy of these accepters is deviated from that given by the effective mass theory. in this report, wurtzite gan is grown by the molecular-beam epitaxy method, and the photoluminescence spectra were measured. three main peaks are assigned to the donor-acceptor transitions from two kinds of accepters. some of the transitions were identified as coming from the cubic phase of gan, which appears randomly within the predominantly hexagonal material.
