An extended computational approach for point-defect equilibria in semiconductor materials
npj Computational Materials, 2022 Concentrations of intrinsic and extrinsic point defects in crystalline materials with a bandgap are typically calculated in a constant-μ approach from defect formation energies based on density functional theory. In this work, calculations of thermal and

Figure of merit for design of ε-near-zero metamaterials with enhanced Kerrtype nonlinearities [PDF]
EPJ Web of Conferences, 2023 Metamaterials are artificial media designed to display properies going beyond those of ordinary materials. Particularly interesting are ε-near-zero (ENZ) media with real part of the permittivity going to zero in a certain spectral range.

Controlled Synthesis of Carbon-Encapsulated Copper Nanostructures by Using Smectite Clays as Nanotemplates [PDF]
, 2012 Rhomboidal and spherical metallic-copper nanostructures were encapsulated within well-formed graphitic shells by using a simple chemical method that involved the catalytic decomposition of acetylene over a copper catalyst that was supported on different ...
