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

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 …

We study the evolution of the band gap structure in few-layer MoTe2 crystals, by means of
low-temperature microreflectance (MR) and temperature-dependent photoluminescence …

Monolayer transition-metal dichalcogenides have recently emerged as possible candidates
for valleytronic applications, as the spin and valley pseudospin are directly coupled and …

We present optical spectroscopy (photoluminescence and reflectance) studies of thin layers
of the transition metal dichalcogenide WSe2, with thickness ranging from mono-to tetra-layer …

We present the micro-photoluminescence (μPL) and micro-reflectance contrast (μRC)
spectroscopy studies on thin films of MoSe2 with layer thicknesses ranging from a …

Faraday rotation is a fundamental effect in the magneto-optical response of solids, liquids
and gases. Materials with a large Verdet constant find applications in optical modulators …

Coulomb interactions are crucial in determining the ground state of an ideal two-
dimensional electron gas (2DEG) in the limit of low electron densities. In this regime …

Semiconducting transition metal dichalcogenides (TMDCs) give rise to interesting new
phenomena in external magnetic fields, such as valley Zeeman splitting and magnetic-field …

Monolayers and multilayers of semiconducting transition metal dichalcogenides (TMDCs)
offer an ideal platform to explore valley-selective physics with promising applications in …
