The first-principal simulations are applied to study a photo-induced metastability in amorphous selenium (a-Se) and the contribution of the valence-alteration pair (VAP) defects in this process. The VAP defect is confirmed to be the equilibrium defec

The first principles calculations (GGA) have been applied to study the crystallographic defects in $\alpha$-PbO in order to understand an origin of $n$- and $p$-type conductivity in otherwise undoped $\alpha$-PbO. It was found that deposition in the

Here we propose to induce magnetism in semiconductor utilizing the unique properties of the interstitial defect to act as the magnetic impurity within the alpha-PbO crystal structure. The Pbi interstitial generates the p-localized state with two on-s

A new route to $d^0$ magnetism is established with help of the first principles methods. Non-magnetic interstitial impurities from group 14 in the periodic table are found to induce $p$-orbital magnetism in polycrystalline PbO-type structures. The ha

We introduce a self-passivation of single lead (Pb) and oxygen (O) vacancies in the \alpha-PbO compound through formation of a Pb-O vacancy pair. The preferential mechanism for pair formation involves initial development of the single Pb vacancy whic

The electronic properties of polycrystalline lead oxide consisting of a network of single-crystalline $\alpha$-PbO platelets and the formation of the native point defects in $\alpha$-PbO crystal lattice are studied using first principles calculations

The effect of mispair on charge transport in a DNA of sequence (GC)(TA)_N(GC)_3 connected to platinum electrodes is studied using the tight-binding model. With parameters derived from ab initio density functional result, we calculate the current vers

In this review, we provide an in-depth description of the physics of monolayer and bilayer graphene from a theorist's perspective. We discuss the physical properties of graphene in an external magnetic field, reflecting the chiral nature of the quasi
