【摘要】 用紧束缚近似线性Muffin-tin轨道的方法计算了稀磁半导体(In1-xMnx)As(x=1/2,1/4和1/8)的晶格常数,磁性和电子结构.给出了Mn掺杂浓度的变化对(In1-xMnx)As的晶格常数,磁性和电子结构的影响.
【Abstract】 Lattice constants magnetic and electronic structures of diluted magnetic semiconductors(In1-x,Mnx)As(x=1/2,1/4,1/8) are investigated using the first principles LMTO-ASA band calculation.We show here the effect of varying Mn concentrations on the lattice constants,magnetic and the electronic structures.
