Deep-Learning-Enabled Fast Optical Identification and Characterization of Two-Dimensional Materials
Bingnan Han, Yuxuan Lin, Yafang Yang +22
Advanced microscopy and/or spectroscopy tools play indispensable role in nanoscience and nanotechnology research, as it provides rich information about the growth mechanism, chemic…
Electrical homogeneity of large-area chemical vapor deposited multilayer hexagonal boron nitride sheets
Fei Hui, Wenjing Fang, Wei Sun Fang +7
Hexagonal boron nitride (h-BN) is a two dimensional (2D) layered insulator with superior dielectric performance that offers excellent interaction with other 2D materials (e.g. grap…
Origin of Contact Resistance at Ferromagnetic Metal-Graphene Interfaces
Khoong Hong Khoo, Wei Sun Leong, John T. L. Thong +1
Edge contact geometries are thought to yield ultralow contact resistances in most non-ferromagnetic metal-graphene interfaces owing to their large metal-graphene coupling strengths…
Tuning the Threshold Voltage of MoS2 Field-Effect Transistors via Surface Treatment
Wei Sun Leong, Yida Li, Xin Luo +3
Controlling the threshold voltage (Vth) of a field-effect transistor is important for realizing robust logic circuits. Here, we report a facile approach to achieve bidirectional Vt…
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…
Gold on WSe2 Single Crystal Film as a Substrate for Surface Enhanced Raman Scattering (SERS) Sensing
Bablu Mukherjee, Wei Sun Leong, Yida Li +5
Synthesis and characterization of high-quality single-crystal WSe2 films on highly-insulating substrate is presented. We demonstrate for the first time that the presence of gold na…
