Abstract The optical properties of atomically thin transition metal dichalcogenides (TMDCs) are dominated by Coulomb bound quasi-particles, such as excitons, trions, and biexcitons. Due to the number and density of possible states, attributing different spectral peaks to the specific origin can be difficult. In particular, there has been much conjecture around the presence, binding energy and/or nature of biexcitons in these materials. In this work, we remove any ambiguity in identifying and separating the optically excited biexciton in monolayer WS2 using two-quantum multidimensional coherent spectroscopy (2Q-MDCS), a technique that directly and selectively probes doubly-excited states, such as biexcitons. The energy difference between the unbound two-exciton state and the biexciton is the fundamental definition of biexciton binding energy and is measured to be 26 ± 2 meV. Furthermore, resolving the biexciton peaks in 2Q-MDCS allows us to identify that the biexciton observed here is composed of two bright excitons in opposite valleys.

Biexciton Binding Energy

The method of few-body physics is applied to treat a system of two excitons in a quantum disk. The binding energy of a biexciton is calculated for various confinements. It is found that the biexciton binding energy drops sharply to zero, i.e. there exists a critical radius RC, such that if R>RC (R<RC), the biexciton configuration is stable (unstable). From [Formula: see text], we obtain RC~0.5[Formula: see text], indicating the existence of a repulsive core of interaction between the two neutral excitons. The dependence of the ratio of biexciton binding energy to that of the exciton on the disk thickness is also investigated.
