Structural, morphological, and optoelectrical characterization of Bi2S3 thin films grown by co-evaporation

This work presents the results of synthesis and characterization of polycrystalline n-type Bi2S3 thin films. The films were grown through a chemical reaction from co-evaporation of their precursor elements in a soda-lime glass substrate. The effect of the experimental conditions on the optical, morp...
