InGaN light-emitting diodes (LEDs) are more efficient and cost effective than incandescent and fluorescent lighting, but lattice mismatch limits the thickness of InGaN layers that can be grown on GaN without performance-degrading dislocations. In this work, we apply hybrid density functional theory calculations to investigate the thermodynamic stability, lattice parameters, and band gaps of wurtzite and zincblende quaternary BInGaN alloys. We find that the wurtzite phase is more stable and can…

Algorithms for the Generation of Generalized Monkhorst-Pack Grids
This paper presents algorithms that can rapidly generate the optimized generalized Monkhorst Pack grid both dynamically and using a pre-generated database, and incorporates designs to maximally accelerate such searches.
Algorithms and Code for the Generation of Generalized Monkhorst-Pack Grids.
This paper presents algorithms that can rapidly generate optimized generalized Monkhorst Pack grids both dynamically and using a pre-generated database, and the grids returned by these algorithms are more efficient than those generated by previously reported algorithms.


BInGaN alloys nearly lattice-matched to GaN for high-power high-efficiency visible LEDs
InGaN-based visible light-emitting diodes (LEDs) find commercial applications for solid-state lighting and displays, but lattice mismatch limits the thickness of InGaN quantum wells that can be grown
GaAs1−y−zPyBiz, an alternative reduced band gap alloy system lattice-matched to GaAs
The growth and properties of alloys in the alternative quaternary alloy system GaAs1−y−zPyBiz were explored. This materials system allows simultaneous and independent tuning of lattice constant and
Optical properties and temperature dependence of the interband transitions of cubic and hexagonal GaN.
Average properties, such as the effective ir dielectric constant and the effective number of valence electrons per atom are calculated for the two polytypes and compared to GaAs and GaP.
Band bowing and band alignment in InGaN alloys
We use density functional theory calculations with the HSE06 hybrid exchange-correlation functional to investigate InGaN alloys and accurately determine band gaps and band alignments. We find a
Valence-band splittings in cubic and hexagonal AlN, GaN, and InN
Modern parameter-free band-structure calculations are applied to the uppermost valence bands near the Γ point. They are based on a nonlocal exchange-correlation starting point for the iteration of
Auger recombination in InGaN measured by photoluminescence
The Auger recombination coefficient in quasi-bulk InxGa1−xN (x∼9%–15%) layers grown on GaN (0001) is measured by a photoluminescence technique. The samples vary in InN composition, thickness, and

Temperature dependent photo-modulated reflectance is used to measure the band gap Eg and spin-orbit splitting energy ∆so in dilute-Bi In0.53Ga0.47As1-xBix/InP for 1.2% = x = 5.8%. At room
Growth of coherent BGaN films using BBr3 gas as a boron source in plasma assisted molecular beam epitaxy
Incorporating boron into gallium nitride to make BxGa1-xN solid solutions would create an avenue for extreme alloys due to the fact that wurtzite phase BN has a larger band gap and smaller lattice
