A lack of inversion symmetry coupled with the presence of time‐reversal symmetry endows
2D transition metal dichalcogenides with individually addressable valleys in momentum …

Recent results on the optical properties of monolayer and few layers of semiconducting
transition metal dichalcogenides are reviewed. Experimental observations are presented …

An outstanding challenge in quantum photonics is scalability, which requires positioning of
single quantum emitters in a deterministic fashion. Site positioning progress has been made …

The target of valleytronics developments is to manipulate the valley degree of freedom and
utilize it in microelectronics as charge and spin degrees of freedom. Based on first-principles …

We present low-temperature magneto-photoluminescence experiments which demonstrate
the brightening of dark excitons by an in-plane magnetic field B applied to monolayers of …

Two-dimensional semiconducting transition metal dichalcogenides (TMDCs) have recently
become attractive materials for several optoelectronic applications, such as photodetection …

Optical properties of atomically thin transition metal dichalcogenides are controlled by robust
excitons characterized by a very large oscillator strengths. Encapsulation of monolayers …

By implementing four-wave mixing (FWM) microspectroscopy, we measure coherence and
population dynamics of the exciton transitions in monolayers of MoSe2. We reveal their …

Recently, the emerging conceptual valley-related devices have attracted much attention due
to the progress on generating, controlling, and detecting the valley degree of freedom in the …

We present a detailed investigation of the exciton and trion dynamics in naturally doped
MoSe 2 and WSe 2 single atomic layers as a function of temperature in the range 10–300 K …
