Abstract

Electron-hole liquids (EHLs), a correlated state of matter and a thermodynamic liquid, have recently been found to exist at room temperature in suspended monolayers of MoS2. This paper shows that leveraging valley physics in MoS₂ may provide tunability of EHL characteristics such as emission wavelength, linewidth, and liquid density. Using a simple model for free excitons and correlated plasma, the authors argue that a phase transition into the EHL state may be feasible in substrate-supported monolayer samples and explore the effect of valley polarization on binding energy, density, and linewidth.
