Contact Research Strategy for Emerging Molybdenum Disulfide and Other Two-Dimensional Field-effect Transistors
Yuchen Du, Lingming Yang, Han Liu +1
Layered two-dimensional (2D) semiconducting transition metal dichalcogenides (TMD) have been widely isolated, synthesized, and characterized recently. Numerous 2D materials are ide…
Chloride Molecular Doping Technique on 2D Materials: WS2 and MoS2
Lingming Yang, Kausik Majumdar, Han Liu +8
Low-resistivity metal-semiconductor (M-S) contact is one of the urgent challenges in the research of 2D transition metal dichalcogenides (TMDs). Here, we report a chloride molecula…
High-Performance MoS2 Field-Effect Transistors Enabled by Chloride Doping: Record Low Contact Resistance (0.5 kohm*um) and Record High Drain Current (460 uA/um)
Lingming Yang, Kausik Majumdar, Yuchen Du +8
In this paper, we report a novel chemical doping technique to reduce the contact resistance (Rc) of transition metal dichalcogenides (TMDs) - eliminating two major roadblocks (name…
MoS2 Field-effect Transistors with Graphene/Metal Heterocontacts
Yuchen Du, Lingming Yang, Jingyun Zhang +4
For the first time, n-type few-layer MoS2 field-effect transistors with graphene/Ti as the hetero-contacts have been fabricated, showing more than 160 mA/mm drain current at 1 μm g…
