Enhanced photoelectric performance of BiOSe/CuInPS heterojunction ferroelectric polarization in two-dimensional CuInPS.

Two-dimensional (2D) materials have drawn tremendous interest as promising materials for photoelectric devices due to their extraordinary properties. As an outstanding 2D photoelectric material, BiOSe (BOS) has exhibited good performance and great potential in photoelectric applications. In this report, we have constructed a photoelectric heterojunction based on BOS and CuInPS (CIPS) nanosheets to achieve enhanced photoelectric performance.
