Unfolding the band structure of disordered solids: from bound states to high-mobility Kane fermions

O. Rubel, A. Bokhanchuk, S. J. Ahmed +1

Supercells are often used in ab initio calculations to model compound alloys, surfaces and defects. One of the main challenges of supercell electronic structure calculations is to…

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…

Single-carrier impact ionization favored by a limited band dispersion

A. Darbandi, O. Rubel

A critical requirement for high gain and low noise avalanche photodiodes is the single-carrier avalanche multiplication. We propose that the single-carrier avalanche multiplication…

Unipolar Time-Differential Pulse Response with a Solid-State Charpak Photoconductor

A. H. Goldan, O. Tousignant, K. S. Karim +1

We demonstrate, for the first time, a high granularity multi-well solid-state detector (MWSD) with the unipolar time-differential property for ultrafast pulse response. Results sho…
