Switching Mechanism in Single-Layer Molybdenum Disulfide Transistors: an Insight into Current Flow across Schottky Barriers
Han Liu, Mengwei Si, Yexin Deng +6
In this article, we study the properties of metal contacts to single-layer molybdenum disulfide (MoS2) crystals, revealing the nature of switching mechanism in MoS2 transistors. On…
Temperature-dependent Phonon Shifts in Monolayer MoS2
Nicholas Lanzillo, A. Glen Birdwell, Matin Amani +9
We present a combined experimental and computational study of two-dimensional molybdenum disulfde (MoS2) and the effect of temperature on the frequency shifts of the Raman-active E…
Blue shifting of the A exciton peak in folded monolayer 1H-MoS2
Frank J. Crowne, Matin Amani, A. Glen Birdwell +7
The large family of layered transition-metal dichalcogenides is widely believed to constitute a second family of two-dimensional (2D) semiconducting materials that can be used to c…
Statistical Study of Deep Sub-Micron Dual-Gated Field-Effect Transistors on Monolayer CVD Molybdenum Disulfide Films
Han Liu, Mengwei Si, Sina Najmaei +5
Monolayer Molybdenum Disulfide (MoS2) with a direct band gap of 1.8 eV is a promising two-dimensional material with a potential to surpass graphene in next generation nanoelectroni…
Second harmonic microscopy of monolayer MoS2
Nardeep Kumar, Sina Najmaei, Qiannan Cui +4
We show that the lack of inversion symmetry in monolayer MoS2 allows strong optical second harmonic generation. Second harmonic of an 810-nm pulse is generated in a mechanically ex…
Vapor Phase Growth and Grain Boundary Structure of Molybdenum Disulfide Atomic Layers
Sina Najmaei, Zheng Liu, Wu Zhou +7
Single layered molybdenum disulfide with a direct bandgap is a promising two-dimensional material that goes beyond graphene for next generation nanoelectronics. Here, we report the…
