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…
Low-Contact-Resistance Graphene Devices with Nickel-Etched-Graphene Contacts
Wei Sun Leong, Hao Gong, John T. L. Thong
The performance of graphene-based transistors is often limited by the large electrical resistance across the metal-graphene contact. We report an approach to achieve ultra-low resi…
