摘要:

本文报道了铁磁半导体材料(Ga,Mn)As有效态密度的电学测量。通过分析由于增强的电子-电子相互作用而引起的电导率校正,提取了不同维数的(Ga,Mn)As样品的电扩散常数。使用爱因斯坦关系允许推导出在费米能量下的(Ga,Mn)As的有效态密度。

英文摘要:

We report on electrical measurements of the effective density of states in the ferromagnetic semiconductor material (Ga,Mn)As. By analyzing the conductivity correction due to enhanced electron-electron interaction the electrical diffusion constant was extracted for (Ga,Mn)As samples of different dimensionality. Using the Einstein relation allows to deduce the effective density of states of (Ga,Mn)As at the Fermi energy.
