Electronic and optical properties of boron containing GaN alloys: The role boron atom clustering
Cara-Lena Nies, Thomas P. Sheerin, Stefan Schulz
Boron (B) containing III-nitride materials, such as wurtzite (B,Ga)N alloys, have recently attracted significant interest to tailor the electronic and optical properties of optoele…
Impact of random alloy fluctuations on the carrier distribution in multi-color (In,Ga)N/GaN quantum well systems
Michael O'Donovan, Patricio Farrell, Julien Moatti +3
In this work, we study the impact that random alloy fluctuations have on the distribution of electrons and holes across the active region of a (In,Ga)N/GaN multi-quantum well based…
Impact of random alloy fluctuations on the electronic and optical properties of (Al,Ga)N quantum wells: Insights from tight-binding calculations
Robert Finn, Stefan Schulz
Light emitters based on the semiconductor alloy aluminium gallium nitride ((Al,Ga)N) have gained significant attention in recent years due to their potential for a wide range of ap…
Multiscale simulations of uni-polar hole transport in (In,Ga)N quantum well systems
Michael O'Donovan, Patricio Farrell, Timo Streckenbach +2
Understanding the impact of the alloy micro-structure on carrier transport becomes important when designing III-nitride-based LED structures. In this work, we study the impact of a…
Fully analytic valence force fields for the relaxation of group-IV semiconductor alloys: elastic properties of group-IV materials calculated from first principles
Daniel S. P. Tanner, Christopher A. Broderick, Amy C. Kirwan +2
SiGe(C,Sn,Pb) alloys have attracted significant attention as a route to achieve a direct-gap group-IV semiconductor. Using density functional theory (DFT) - e…
Indium gallium nitride quantum dots: Consequence of random alloy fluctuations for polarization entangled photon emission
Saroj Kanta Patra, Stefan Schulz
We analyze the potential of the -plane InGaN/GaN quantum dots for polarization entangled photon emission by means of an atomistic many-body framework. Special attention is paid…
