Pressure-dependent bandgap study of MBE grown {CdO/MgO} short period SLs using diamond anvil cell
Abinash Adhikari, Pawel Strak, Piotr Dluzewski +2
Semiconductor superlattices have found widespread applications in electronic industries. In this work, short-period superlattice structure (SLs) composed of CdO and MgO layers was…
Coulomb contribution to Shockley-Read-Hall (SRH) recombination
Konrad Sakowski, Pawel Strak, Pawel Kempisty +6
Defect-mediated nonradiative recombination, known as Shockley-Read-Hall (SRH) recombination is reformulated. The introduced model considers Coulomb attraction between charged deep…
Polarization doping ab initio verification of the concept charge conservation and nonlocality
Ashfaq Ahmad, Pawel Strak, Pawel Kempisty +10
In this work, we study the emergence of polarization doping in AlxGa1-xN layers with graded composition from a theoretical viewpoint. We demonstrate that the charge conservation la…
Spontaneous emission of color centers at 4eV in hexagonal boron nitride under hydrostatic pressure
Kamil Koronski, Agata Kaminska, Nikolai D. Zhigadlo +3
The light emission properties of color centers emitting in 3.3-4 eV region are investigated for hydrostatic pressures ranging up to 5GPa at liquid helium temperature. The light emi…
Exact method of determination of the recombination mode from time resolved photoluminescence data
Pawel Strak, Kamil Koronski, Kamil Sobczak +7
A method of data analysis is proposed for the determination of the carrier recombination processes in optically excited matter measured by time-resolved photoluminescence, differen…
Lattice parameters and stability of the spinel compounds in relation to the ionic radii and electronegativities of constituting chemical elements
M. G. Brik, A. Suchocki, A. Kamińska
A thorough consideration of the relation between the lattice parameters of 185 binary and ternary spinel compounds, on one side, and ionic radii and electronegativities of the cons…
