LLE Review, Volume 101 35 Introduction and Motivation The development of optics for new applications is based on the use of materials that have the appropriate mechanical and optical properties. For infrared (IR) window and dome materials that protect imaging systems against damaging conditions, three main considerations are taken into account: material strength, thermal-shock resistance, and o...
Nano energetic materials have attracted great attention recently owing to their potential applications for both civilian and military purposes. By introducing silicon microchannel plates (Si-MCPs) three-dimensional (3D)-ordered structures, monocrystalline MnMoO4 with a size of tens of micrometres and polycrystalline MnMoO4 nanoflakes are produced on the surface and sidewall of nickel-coated Si-...
Vanadium dioxide (VO2) exhibits a reversible insulator-metal phase transition that is of significant interest in energy-efficient nanoelectronic and nanophotonic devices. In these applications, crystalline materials are usually preferred for their superior electrical transport characteristics as well as spatial homogeneity and low surface roughness over the device area for reduced scattering. H...
We report on the development of a finite element method based computational framework for evaluating thermoelectric properties polycrystalline nanostructured materials and composites at mesoscale. This effort was advanced by formulation, testing (if possible) validation ‘benchmark problems,’ that progressed from simple to more cases. The following benchmark problems were investigated: (a) effec...
