## Description

- description: The enhanced Coulomb interaction in two-dimensional (2D) semiconductors
    leads to the tightly bound electron-hole pairs known as excitons. The large binding
    energy of excitons enables the formation of Rydberg excitons with high principal
    quantum numbers (n), analogous to Rydberg atoms. Rydberg excitons possess strong
    interactions among themselves, as well as sensitive responses to external stimuli.
    Here, we probe Rydberg exciton resonances through photocurrent spectroscopy in
    a monolayer WSe<sub>2</sub> p-n junction formed by a split-gate geometry. We show
    that an external in-plane electric field not only induces a large Stark shift
    of Rydberg excitons up to quantum principal number n=3 but also mixes different
    orbitals and brightens otherwise dark states such as 3p and 3d. Our study provides
    an exciting platform for engineering Rydberg excitons for new quantum states and
    quantum sensing.
