Study of morphology effects on magnetic interactions and band gap variations for 3 late transition metal bi-doped ZnO nano structures by hybrid DFT calculations
Soumendu Datta, Gopi Chandra Kaphle, Sayan Baral +1
Using density functional theory (DFT) based electronic structure calculations, the effects of morphology of semiconducting nano structures on the magnetic interaction between two m…
Enhanced magnetism of Cu clusters capped with N and endohedrally doped with Cr
Soumendu Datta, Radhashyam Banerjee, Abhijit Mookerjee
The focus of our work is on the production of highly magnetic materials out of Cu clusters. We have studied the relative effects of N-capping as well as N mono-doping on the struct…
Anderson transitions in disordered two-dimensional lattices
Dayasindhu Dey, Manoranjan Kumar, Pragya Shukla
We numerically analyze the energy level statistics of the Anderson model with Gaussian site disorder and constant hopping. The model is realized on different two-dimensional lattic…
Effect of doping on the electronic properties of Graphene and T-graphene : A theoretical approach
Banasree Sadhukhan, Arabinda Nayak, Abhijit Mookerjee
In this communication we present together four distinct techniques for the study of electronic structure of solids : the tight-binding linear muffin-tin orbitals (TB-LMTO), the rea…
Negative partial density of states in mesoscopic systems
Urbashi Satpathi, P. Singha Deo
Since the experimental observation of quantum mechanical scattering phase shift in mesoscopic systems, several aspects of it has not yet been understood. The experimental observati…
