Abstract

This study examines the photogalvanic effect in three distinct isomers of BeP2 monolayers. The results demonstrated that 1H-BeP2 monolayer possesses pronounced anisotropy on photocurrents along the armchair and zigzag directions, whereas penta-BeP2 and planar-BeP2 monolayers exhibit distinctive photocurrent responses. Furthermore, there presents that defect engineering can markedly enhance the photogalvanic effect in three BeP2 photodetectors. It is noteworthy that the 1H-BeP2-zigzag photodetector exhibits exceptional sensitivity on polarization detection. Therefore, this study not only broadens the scope for the applications of BeP2 monolayers in the fields of optoelectronics and nanoelectronics, but also highlights their significant values in the detection of polarization.
