A first-principle Study of (Ga,Mn)As-based Dilute Magnetic Semiconductors

In this work, we performed a first-principle Density Functional Theory (DFT) study to investigate the structural, electronic, and magnetic properties of Mn-doped GaAs in the dilute limit. (Ga,Mn)As is one of the representing example of Dilute Magnetic Semiconductors (DMS). Here, after providing a brief review of DMS and their magnetic mechanism, we have discussed our results and the methods employed to obtain the result. Our results corroborate earlier ab-initio investigations and offer novel perspective on the electronic structure of (Ga,Mn)As.
