Two dimensional (2D) transition-metal dichalcogenide (TMD) based semiconductors have generated intense recent interest due to their novel optical and electronic properties, and potential for applications. In this work, we characterize the atomic and electronic nature of intrinsic point defects found in single crystals of these materials synthesized by two different methods - chemical vapor transport and self-flux growth. Using a combination of scanning tunneling microscopy (STM) and scanning…

Magnetism in semiconducting molybdenum dichalcogenides
2H-MoTe2 and 2H- MoSe2 are established as a new class of magnetic semiconductors and open a path to studying the interplay of 2D physics and magnetism in these interesting semiconductor materials.
Oxidation of Monolayer WS2 in Ambient is a Photoinduced Process.
The strong wavelength dependence and apparent lack of irradiance dependence suggests that ambient oxidation of WS2 is initiated by photon-mediated electronic band transitions, that is, photo-oxidation.
Optical generation of high carrier densities in 2D semiconductor heterobilayers
By tuning the optical excitation density above the Mott threshold, the phase transition from interlayer excitons to charge-separated electron/hole plasmas is realized, where photoexcited electrons and holes are localized to individual layers.
Enhancing functionalities of atomically thin semiconductors with plasmonic nanostructures
Abstract Atomically thin, two-dimensional, transition-metal dichalcogenide (TMD) monolayers have recently emerged as a versatile platform for optoelectronics. Their appeal stems from a tunable direct
Nano-imaging of intersubband transitions in van der Waals quantum wells
This work employs near-field local probing to spectrally resolve intersubband transitions with a nanometre-scale spatial resolution and electrostatically control the absorption and enables the exploitation of intersub band transitions with unmatched design freedom and individual electronic and optical control suitable for photodetectors, light-emitting diodes and lasers.
Deterministic coupling of site-controlled quantum emitters in monolayer WSe2 to plasmonic nanocavities
A deterministic approach to achieve Purcell enhancement at lithographically defined locations using the sharp corners of a metal nanocube for both electric field enhancement and to deform a 2D material is demonstrated.

Investigation of temperature-dependent photoluminescence in multi-quantum wells
The origin of the anomalous increase of integrated PL intensity proved to be associated with the enhancement of carrier drifting because of the increase of carrier mobility in the temperature range from 15’K to 100 K.
Dark excitons and the elusive valley polarization in transition metal dichalcogenides
A rate equation model for the dark and bright excitons kinetics is proposed which explains the wide variation in the observed degree of circular polarization of the PL emission in different TMDs
