Multi-terminal electrical transport measurements of molybdenum disulphide using van der Waals heterostructure device platform
Xu Cui, Gwan-Hyoung Lee, Young Duck Kim +15
Atomically thin two-dimensional (2D) semiconductors such as molybdenum disulphide (MoS2) hold great promise in electrical, optical, and mechanical devices and display novel physica…
Gate-Tunable Resonant Tunneling in Double Bilayer Graphene Heterostructures
Babak Fallahazad, Kayoung Lee, Sangwoo Kang +10
We demonstrate gate-tunable resonant tunneling and negative differential resistance in the interlayer current-voltage characteristics of rotationally aligned double bilayer graphen…
Tunneling transport in a few monolayer-thick WS2/graphene heterojunction
Takehiro Yamaguchi, Rai Moriya, Yoshihisa Inoue +5
This paper demonstrates the high-quality tunnel barrier characteristics and layer number controlled tunnel resistance of a transition metal dichalcogenide (TMD) measuring just a fe…
Characterization and manipulation of individual defects in insulating hexagonal boron nitride using scanning tunneling microscopy
Dillon Wong, Jairo Velasco, Long Ju +9
Defects play a key role in determining the properties of most materials and, because they tend to be highly localized, characterizing them at the single-defect level is particularl…
Accessing the transport properties of pristine few-layer black phosphorus by van der Waals passivation in inert atmosphere
Rostislav A. Doganov, Eoin C. T. O'Farrell, Steven P. Koenig +9
Ultrathin black phosphorus, or phosphorene, is the second known elementary two-dimensional material that can be exfoliated from a bulk van der Waals crystal. Unlike graphene it is…
Electrical characterization of fully encapsulated ultra thin black phosphorus-based heterostructures with graphene contacts
Ahmet Avsar, Ivan J. Vera-Marun, Tan Jun You +4
The presence of finite bandgap and high mobility in semiconductor few-layer black phosphorus offers an attractive prospect for using this material in future two-dimensional electro…
