Broad Band Optical Properties of Large Area Monolayer CVD Molybdenum Disulfide
Wei Li, A. Glen Birdwell, Matin Amani +9
Recently emerging large-area single-layer MoS2 grown by chemical vapor deposition has triggered great interest due to its exciting potential for applications in advanced electronic…
Valley-selective optical Stark effect in monolayer WS2
Edbert J. Sie, James W. McIver, Yi-Hsien Lee +3
Breaking space-time symmetries in two-dimensional crystals (2D) can dramatically influence their macroscopic electronic properties. Monolayer transition-metal dichalcogenides (TMDs…
Trion induced negative photoconductivity in monolayer MoS2
C. H. Lui, A. J. Frenzel, D. V. Pilon +5
Optical excitation typically enhances electrical conduction and low-frequency radiation absorption in semiconductors. We have, however, observed a pronounced transient decrease of…
Semiconducting-to-metallic photoconductivity crossover and temperature-dependent Drude weight in graphene
A. J. Frenzel, C. H. Lui, Y. C. Shin +2
We investigated the transient photoconductivity of graphene at various gate-tuned carrier densities by optical-pump terahertz-probe spectroscopy. We demonstrated that graphene exhi…
Electronic transport and device prospects of monolayer molybdenum disulphide grown by chemical vapour deposition
Wenjuan Zhu, Tony Low, Yi-Hsien Lee +5
Layered transition metal dichalcogenides display a wide range of attractive physical and chemical properties and are potentially important for various device applications. Here we…
