However, in solids, these energy levels combine to form bands. Those electrons that are used to bind the atoms are present in the valence energy band, whereas the leftover electrons are able to move freely around. For many materials, there is an energy gap between the two bands. The ...
Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion. On the other hand, heat transfer in solids is due to the combination of lattice vibrations of the molecules and the energy transport by free electrons. For example,...

Full size image In Fig. 3, we show that the valley splitting enhancements observed in Fig. 2 are robust to imperfect implementation of the STRAWW wavelength λ = 1.68 nm. Plotting EVS as a function of λ and \({\bar{n}}_{{{\rm{Ge}}}\) in Fig. 3a, or εxy in Fig....
Full size image The structures of Li2+xZrCl6-xOxare complex with intrinsic vacancies or partial occupation at all sites. Energetically most stable structures are needed to compute the key properties of electrolyte like phase stability, thermodynamic stability, and ionic transport. To have detailed ...
Full size image 2.2Additive Manufacturing AlSi10Mg Alloy Gradient Metamaterials Gradient metamaterial samples of AlSi10Mg alloy, measuring 40 mm × 40 mm × 40 mm in dimensions, were fabricated by utilizing a commercial LPBF machine (E-PLUS-3D Inc., EP-M650P) equipped with a Yb-fiber...
Full size image Austin and Mott have investigated a model for the hopping conductivity in a nanocrystalline semiconductor material [14]. They proposed that the conduction between localized states is owing to SPH [14,27]. In the non-adiabatic hopping process, the pre-exponential factor σ0(in Eq...
