| In experiment, Arsenic evaporates easily so the single crystal, which is produced from polycrystal which is synthesized in stoichiometric ratio, may change the band gap of this crystal and further affects optical transmittance of single crystal. Therefore, during the synthesis, the content of Arsenic will increase to make it deviate from the stoichiometric ratio. |
