Dissociation of two-dimensional excitons in monolayer WSe2

Dissociation of two-dimensional excitons in monolayer WSe2

In two-dimensional semiconductors excitons are strongly bound, suppressing the creation of free carriers. Here, the authors investigate the main exciton dissociation pathway in p-n junctions of monolayer WSe2 by means of time and spectrally resolved photocurrent measurements.
