Forcrystalline silicon, the band-gap energy is 1.1 electron-volts (eV). OtherPV cell materialshave band-gap energies ranging from 1 to 3.3eV[64,65]. Moreover, in recent studies, researchers are trying to find the optimum use of band gaps in a multi-junction device using several techniques...

First-principles calculation based on density functional theory (DFT) with the generalized gradient approximation (GGA) were carried out to investigate the energy band gap structure of Si and Ge nanofilms. Calculation results show that the band gaps of Si(111) and Ge(110) nanofilms are indirect ...
Band gap energy of AgNPs is depended on the size of the particles. Several studies reported that the band gap energy of NPs is inversely proportional to the size of the particles, which means smaller size of the particles lead to the higher band gap energy. Band gap energy of AgNPs was ...
The structure and electronic properties of Ge/SiC van der Waals (vdW) bilayer under the influence of an electric field have been investigated by the first-principles method. Without an electric field, the system shows a small band gap of 126 meV at the equilibrium state. Interestingly, by app...
(0.80 eV) is explained by band gap narrowing from high doping in n+-top layer. A superlinear increase of EL with current density is explained by a rising ratio of direct/indirect electron densities when quasi Fermi energy level rises into the conduction band. An analytical model for the ...
The pressure dependence of the band gap energy of the dilute nitride GaNP is analyzed. It is found that the pressure dependence of the Г conduction band minimum (CBM) is stronger than that of the X CBM. We also find that the energy difference between the X CBM and the Г CBM in GaN...
Indeed, the electronic structure of a semiconductor is characterized by a conduction band (CB) and a valence band (VB) separated by a band gap of energy (Eg). From: Membrane Reactors for Energy Applications and Basic Chemical Production, 2015 ...
Band gap, in solid-state physics, a range of energy levels within a given crystal that are impossible for an electron to possess. Generally, a material will have several band gaps throughout its band structure (the continuum of allowed and forbidden elec
