Coherent dynamics and mapping of excitons in single-layer MoSe${}_2$ and WSe${}_2$ at the homogeneous limit

Caroline Boule, Diana Vaclavkova, Miroslav Bartos +6

We perform coherent nonlinear spectroscopy of excitons in single-layers of MoSe${}_2$ and WSe${}_2$ encapsulated between thin films of hexagonal boron nitride. Employing four-wave mixi…
