There are a broad range of applications for narrowband long-wave infrared (LWIR) sources, especially within the 8–12 μm atmospheric window. These include infrared beacons, free-space communications, spectroscopy, and potentially on-chip photonics.

Using an automated optimization scheme, we generate a gallium projector augmented wave (PAW) data set with the 3d electrons treated as core electrons, in contrast to typical treatment of the 3d electrons as valence electrons. Treating the 3d electron

We model the highly reduced thermal conductivity of nanostructured materials observed in nanoribbons. For highly scaled structures, such as wires with diameters on the order of 20 nm, physical effects beyond classical boundary scattering, including a

To improve first-principles calculations of materials properties, we introduce a new metric based on the arctangent of the logderivatives, and demonstrate its effectiveness for evaluating scattering properties of pseudopotentials and projector augmen

A multi-objective genetic algorithm (MOGA) was used to automate a search for optimized pseudopotential parameters. Pseudopotentials were generated using the atomPAW program and density functional theory (DFT) simulations were conducted using the pwPA

The photoluminescence lifetime and spectrum of YBO 3 :Ce 3+ are observed before and after proton bombardment. The optical properties change under irradiation, and thus the material can record information about the radiation exposure. As the fluence o

This study investigates whether particle irradiation of yttrium borate doped with cerium(III) (YBO 3 :1%Ce 3+ ) and yttrium borate doped with europium(III) (YBO 3 :6%Eu 3+ ) can cause displacement damage and whether photoluminescent emission changes

This work examined the sensitivity of the luminescence spectra of europium-doped lanthanum zirconate to different types and amounts of radiation exposure. For the samples and radiation sources used in this work (X-rays and protons), changes in the ph
