Band Offset Measurement Studies on Cu2SnS3/ZnMgO Thin Film Heterojunction |
| 초록 |
We present an investigation of the interface between earth-abundant absorber Cu2SnS3 and ZnMgO buffer layer using photoelectron yield spectroscopy (PYS) as the probing technique. PYS is advantageous for probing electronic structure of the Cu2SnS3/ZnMgO because of the relative long mean long mean free path of photo excited electrons with very low kinetic energy in PYS. The valence-band offset and conduction-band offset is determined for Cu2SnS3/ZnMgO junction with Mg concentration. The related energy band diagram was developed and the obtained results discussed with more elaborated manner. |
