GaSbBi alloys and heterostructures: fabrication and properties
O. Delorme, L. Cerutti, R. Kudrawiec +6
Dilute bismuth (Bi) III-V alloys have recently attracted great attention, due to their properties of band-gap reduction and spin-orbit splitting. The incorporation of Bi into antim…
Phase Transition Induced Carrier Mass Enhancement in 2D Ruddlesden-Popper Perovskites
Michal Baranowski, Szymon J. Zelewski, Mikael Kepenekian +10
There is a variety of possible ways to tune the optical properties of 2D perovskites, though the mutual dependence between different tuning parameters hinders our fundamental under…
Inhomogeneous broadening of optical transitions observed in photoluminescence and modulated reflectance of polar and non-polar InGaN quantum wells
Michał Jarema, Marta Gładysiewicz, Łukasz Janicki +5
In this work the broadening of interband transitions in InGaN/GaN quantum wells (QWs) resulting from structural inhomogeneities is analyzed. The role of polarization-induced electr…
Electronic band structure of nitrogen diluted Ga(PAsN): Formation of the intermediate band, direct and indirect optical transitions, localization of states
Maciej P. Polak, Robert Kudrawiec, Oleg Rubel
The electronic band structure of Ga(PAsN) with a few percent of nitrogen is calculated in the whole composition of Ga(PAs) host using the state-of-the-art density functional method…
On intrinsic Stokes shift in wide GaN/AlGaN polar quantum wells
M. Jarema, M. Gladysiewicz, E. Zdanowicz +3
The interpretation of electromodulated reflectance (ER) spectra of polar quantum wells (QWs) is difficult even for homogeneous structures because of the built-in electric field. In…
Strain and Band-Gap Engineering in Ge-Sn Alloys via P Doping
Slawomir Prucnal, Yonder Berencén, Mao Wang +19
Ge with a quasi-direct band gap can be realized by strain engineering, alloying with Sn, or ultrahigh n-type doping. In this work, we use all three approaches together to fabricate…
