The GGA + U method is applied to calculate the lattice constant and the band gap energy of the As-rich GaBixAs1-x alloy. It is found that the lattice constant almost shows a linear increase as the bismuth fraction increases. The calculated band gap energy is consistent with the experimental data. For the sake of depicting the band gap energy, the v...

Solvent engineering is an important route for improving the quality of solution-processed copper-zinc-tin-sulfur-selenium (CZTSSe) thin films. Here, blended solvents composed of dimethyl sulfoxide (DMSO) and dimethyl formamide (DMF) were used to prepare CZTSSe precursor solution. The addition of DMF improved the wettability of precursor solution on...
