Low-bias Negative Differential Resistance effect in armchair graphene nanoribbon junctions
Suchun Li, Chee Kwan Gan, Young-Woo Son +2
Graphene nanoribbons with armchair edges (AGNRs) have bandgaps that can be flexibly tuned via the ribbon width. A junction made of a narrower AGNR sandwiched between two wider AGNR…
Large magnetoresistance from long-range interface coupling in armchair graphene nanoribbon junctions
Suchun Li, Young-Woo Son, Su Ying Quek
In recent years, bottom-up synthesis procedures have achieved significant advancements in atomically-controlled growth of several-nanometer-long graphene nanoribbons with armchair-…
Low Resistance Metal Contacts to MoS2 Devices with Nickel-Etched-Graphene Electrodes
Wei Sun Leong, Xin Luo, Yida Li +3
We report an approach to achieve low-resistance contacts to MoS2 transistors with the intrinsic performance of the MoS2 channel preserved. Through a dry transfer technique and a me…
Band Structure Mapping of Bilayer Graphene via Quasiparticle Scattering
Matthew Yankowitz, Joel I-Jan Wang, Suchun Li +7
A perpendicular electric field breaks the layer symmetry of Bernal-stacked bilayer graphene, resulting in the opening of a band gap and a modification of the effective mass of the…
Effects of Lower Symmetry and Dimensionality on Raman Spectra in 2D WSe2
Xin Luo, Yanyuan Zhao, Jun Zhang +4
We report the observation and interpretation of new Raman peaks in few-layer tungsten diselenide (WSe2), induced by the reduction of symmetry going from 3D to 2D. In general, Raman…
