The pressure dependence of the energy gap corresponding to allowed optical transitions in germanium has been measured at room temperature and pressures up to 7000 kg/cm 2. This direct energy gap is found to increase at a rate of 1.3 ± 0.1 × 10 5 eV cm 2/ kg, in agreement with ...
The data shows that if silicon elements are replaced by germanium, the H-grabbing energy will be ameliorated. Electromagnetic and thermodynamic properties of SiO, GeO, and SiO-GeO nanoclusters have [...] Open Access Original Research Security Length Associated with the Risk of Ammonia Tank Leak...
The decay can occur only if the mass of the initial nucleus is larger than the one of the final nucleus, and the transition to the state is forbidden or highly suppressed. There are 35 naturally occurring isotopes that can undergo . Two decay modes are usually considered: (i) the standard...
Park et al. reported that MA+loss would become serious when aged temperature over 80 °C, leading to severe cell degradation [30]. Therefore, narrowing the band gap to the ideal band gap of ~ 1.34 eV (based on the SQ limit) for the perovskite is very essential to achieve the maxi...
The field (geometrical) theory of specific heat is based on the universal thermal sum, a new mathematical tool derived from the evolution equation in the Euclidean four-dimensional spacetime, with the closed time coordinate. This theory made it possible
Approaching to a metallic limitation, such as a heavily doped one, the dynamic gets weakened significantly and the intense electron-LO phonon interaction is forbidden21. Figure 2a shows the typical I-V curves for an intrinsic N-Si measured at different magnetic fields. Here, the magnetic field ...
The GaN is mainly prepared through epitaxial growth on a sapphire substrate. Due to the lattice mismatch and thermal mismatch between GaN and the substrate, the prepared material has many defects. Impurities and defects can generate energy levels within the forbidden band, which impacts the physical...
1 Introduction Chalcogenide glasses (ChGs) are formed from periodic table group VI elements, specifically sulfur (S), selenium (Se), and tellurium (Te), that form covalent bonds with elements such as antimony (Sb), arsenic (As), germanium (Ge), bismuth (Bi), tin (Sn), gallium (Ga), ...
FIG. 3 is an energy-band diagram of the strained GeSn quantum well system showing the direct gap, band offsets and composition. DETAILED DESCRIPTION The active material here is a germanium-tin alloy. Experiments have been reported in the literature where several percent of alpha-tin (as much...
