Beginning with the “conventional” two-dimensional (2D) quantum wells based on III–V and II–
VI semiconductors in the 1970s, to the recent atomically thin sheets of van der Waals …

Nowadays, as a result of the emergence of low-dimensional hybrid structures, the scientific
community is interested in their interfacial carrier dynamics, including charge transfer and …

Exciton polaron is a hypothetical many-body quasiparticle that involves an exciton dressed
with a polarized electron-hole cloud in the Fermi sea. It has been evoked to explain the …

Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers
exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This makes …

The 2D MoS2 with superior optoelectronic properties such as high charge mobility and
broadband photoresponse has attracted broad research interests in photodetectors (PD) …

Strong Coulomb interaction in atomically thin transition metal dichalcogenides makes these
systems particularly promising for studies of excitonic physics. Of special interest are the …

Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …

Monolayer transition metal dichalcogenide (TMDC) semiconductors exhibit strong excitonic
optical resonances, which serve as a microscopic, noninvasive probe into their fundamental …

Controlling the density of exciton and trion quasiparticles in monolayer two-dimensional
(2D) materials at room temperature by nondestructive techniques is highly desired for the …

We experimentally demonstrate dressing of the excited exciton states by a continuously
tunable Fermi sea of free charge carriers in a monolayer semiconductor. It represents an …
