Abstract: The effect of the electric field on hydrogen-like states in $\beta$-ZnP$_2$ is investigated. It was found that the exciton states $C_{n=1}$ in the electric field of the Schottky barrier undergo an anomalous Stark shift, and the states that form a reverse hydrogen-like series of absorption lines (IOS) are practically insensitive to the electric field. The laws governing the behavior of the exciton $X_{n=2}$ state “flammable” in an electric field in $\beta$-ZnP$_2$ have been determined.

Keywords: Schottky barrier, exciton, hydrogen-like states, anomalous Stark shift.
