Materials properties of out-of-plane heterostructures of MoS-WSe and WS-MoSe
Bin Amin, Thaneshwor P. Kaloni, Georg Schreckenbach +1
Based on first-principles calculations, the materials properties (structural, electronic, vibrational, and optical properties) of out-of-plane heterostructures formed from the tran…
Linear and non-linear optical response of Mg(x)Zn(1-x)O: A Density Functional study
G. Murtaza, Iftikhar Ahmad, B. Amin +3
Total and partial density of states, frequency dependent complex refractive index including extinction coefficient, optical conductivity and transmission of MgxZn1-xO (0 \leq x \le…
Bandgap engineering of Cd1-xSrxO
I. Khan, Iftikhar Ahmad, B. Amin +2
Structural, electronic and optical properties of Cd1-xSrxO (0 \leq x \leq 1) are calculated for the first time using density functional theory. Our results show that these properti…
Cr doped III-V nitrides: potential candidates for spintronics
B. Amin, S. Arif, Iftikhar Ahmad +4
Studies of Cr-doped III-V nitrides, dilute magnetic alloys, in the zinc-blende crystal structure are presented. The objective of the work is to investigate half-metallicity in Al(0…
Theoretical investigation of half-metallicity in Co/Ni substituted AlN
Suneela Arif, Iftikhar Ahmad, B. Amin
Results of Co and Ni substituted AlN in the zinc blende phase are presented. For spin up states the hybridized N-2p and Co/Ni-3d states form the valance bands with a bandgap around…
Ab-initio study of the bandgap engineering of Al(1-x)Ga(x)N for optoelectronic applications
B. Amin, Iftikhar Ahmad, M. Maqbool +2
A theoretical study of Al(1-x)Ga(x)N, based on full-potential linearized augmented plane wave method, is used to investigate the variations in the bandgap, optical properties and n…
