Highly-Oriented Atomically Thin Ambipolar MoSe Grown by Molecular Beam Epitaxy
Ming-Wei Chen, Dmitry Ovchinnikov, Sorin Lazar +9
Transition metal dichalcogenides (TMDCs), together with other two-dimensional (2D) materials have attracted great interest due to the unique optical and electrical properties of at…
Optospintronics in graphene via proximity coupling
Ahmet Avsar, Dmitrii Unuchek, Jiawei Liu +5
The observation of micron size spin relaxation makes graphene a promising material for applications in spintronics requiring long distance spin communication. However, spin depende…
High Throughput Characterization of Epitaxially Grown Single-Layer MoS2
Foad Ghasemi, Riccardo Frisenda, Dumitru Dumcenco +3
The growth of single-layer MoS2 with chemical vapor deposition is an established method that can produce large-area and high quality samples. In this article, we investigate the ge…
Defect healing and charge transfer mediated valley polarization in MoS/MoSe/MoS trilayer van der Waals heterostructures
Alessandro Surrente, Dumitru Dumcenco, Zhuo Yang +7
Monolayer transition metal dichalcogenides (TMDC) grown by chemical vapor deposition (CVD) are plagued by a significantly lower optical quality compared to exfoliated TMDC. In this…
Dark excitons and the elusive valley polarization in transition metal dichalcogenides
M. Baranowski, A. Surrente, D. K. Maude +7
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…
