英文摘要Calculations of electronic structures and optical properties of mg (or si) and mn co-doped gan were carried out by means of first-principle plane-wave pesudopotential (pwp) based on density functional theory - the spin polarized impurity bands of deep energy levels were found for both systems. they are half metallic and suitable for spin injectors. compared with gan: mn, gan: mn-mg exhibits a significant increase in t(c) 1 while the 1.3 ev absorption peak in gan: mn disappears due to addition of mg. in addition, a strong absorption peak due to (4)t(1) (f) -> (4)t(2) (f) transition of mn(4+) were observed near 1.1 ev. nevertheless, gan: mn-si failed to show increase of t(c), and the absorption peak was not observed at the low energy side.
