The two-step photoexcitation mechanism in a-Se
J. Berashevich, A. Mishchenko, A. Reznik
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…
A proposed new route to d0 magnetism in semiconductors
J. Berashevich, A. Reznik
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 structu…
Origin of n- and p-type conductivity in undoped -PbO: role of defects
J. Berashevich, J. A. Rowlands, A. Reznik
The first principles calculations (GGA) have been applied to study the crystallographic defects in -PbO in order to understand an origin of - and -type conductivity in oth…
Non-magnetic impurities to induce magnetism in -PbO crystal structure
J. Berashevich, A. Reznik
A new route to magnetism is established with help of the first principles methods. Non-magnetic interstitial impurities from group 14 in the periodic table are found to induc…
Self-passivation of vacancies in α-PbO
J. Berashevich, J. A. Rowlands, A. Reznik
We introduce a self-passivation of single lead (Pb) and oxygen (O) vacancies in the α-PbO compound through formation of a Pb-O vacancy pair. The preferential mechanism for pair for…
Lead monoxide -PbO: electronic properties and point defect formation
J. Berashevich, O. Semeniuk, O. Rubel +2
The electronic properties of polycrystalline lead oxide consisting of a network of single-crystalline -PbO platelets and the formation of the native point defects in -PbO cry…
