In the aboveenergy banddiagram, the conduction band is empty whereas the valence band is filled totally. Once the temperature is increased, some heat energy can be supplied to it. So the electrons from the valence band are supplied toward the conduction band by leaving the valence band. Energ...
In intrinsic semiconductors (for instance, pure germanium and silicon) the local levels are absent; however electrical conductivity appears because of the narrowness of the forbidden gap and at moderately high temperature an excitation of electrons from the valence band directly to the conduction band ...
A molecular dynamics simulation method is used to construct the displacement cascades formed in germanium and silicon by self-ions with energy in the range 50500 eV. A simple interatomic potential is presented which empirically accounts for the relative structural difference in the two targets. The ...
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...
A material that has a property of conductor & insulator is known as a semiconductor. The examples are selenium, silicon & germanium. 5). What is the function of semiconductor? It is used to manufacture electronic components like transistors, diodes, and ICs ...

It is well-known that the radiative recombination coefficient Brad of silicon shows a substantial charge carrier density dependence (c-dependence), often modelled via the scaling factor Brel quantified by Altermatt et al. Another effect lowering the total radiative recombination is photon recycling (PR...
