One Dimensional Chain with Long Range Hopping
Chenggang Zhou, R. N. Bhatt
The one-dimensional (1D) tight binding model with random nearest neighbor hopping is known to have a singularity of the density of states and of the localization length at the band…
Reply to cond-mat/0111504
Mona Berciu, R. N. Bhatt
We show that the choice of the sign of the hopping matrix in our impurity band model for disordered III-V diluted magnetic semiconductors [PRL 87, 107293 (2000); cond-mat/0111045]…
Diluted Magnetic Semiconductors in the Low Carrier Density Regime
R. N. Bhatt, Mona Berciu, Malcolm P. Kennett +1
This paper, based on a presentation at the Spintronics 2001 conference, provides a review of our studies on II-VI and III-V Mn-doped Diluted Magnetic Semiconductors. We use simple…
Mean-field approach to ferromagnetism in (III,Mn)V diluted magnetic semiconductors at low carrier densities
Mona Berciu, R. N. Bhatt
We present a detailed study, within the mean-field approximation, of an impurity band model for III-V diluted magnetic semiconductors. Such a model should be relevant at low carrie…
