Synthesis of Nanocrystalline FeS2 with Increased Band Gap for Solar Energy HarvestingSomnath Middya,Animesh Layek,Arka Dey,Partha Pratim RayDepartment of Physics,Jadavpur University摘 要:In this paper,we have reported the synthesis of FeS2 of higher band gap energy(2.75 eV) by using capping reagent and its successive application in organic-inorganic based......
nanoribbons’s energy band and band gap and strain was calculated. The results show that the application of a small uniaxial strain leads to variation of energy subband spacing, which opens a band gap for metallic AGNRs and modifies the band gaps for semiconducting AGNRs near the Fermi level. Energy gap displays linear periodic variation with the strain, and shows obvious shock phenomenon. The maximum......

of ZnO films can be further improved by annealing treatment. The crystallinity of ZnO films becomes better, and the optical gap energy is decreased, but thermoelectric power is enhanced after heat treatment. The optical gap energy decreases from 3.75eV to 3.68eV when the annealing temperature increases from 25℃ to 400℃.This can be ascribed to the decrease of carrier concentration, resulting......
