Narrow-band high-lying excitons with negative-mass electrons in monolayer WSe2

Narrow-band high-lying excitons with negative-mass electrons in monolayer WSe2

Here, the authors report on evidence of an excitonic species formed by electrons in high-energy conduction band states with a negative effective mass, explaining previous observations of quantum interference phenomena in two-dimensional semiconductors.
