Manipulating Steady Heat Conduction by Sensu-shaped Thermal Metamaterials
Tiancheng Han, Xue Bai, Dan Liu +4
The ability to design the control of heat flow has innumerable benefits in the design of electronic systems such as thermoelectric energy harvesters, solid-state lighting, and ther…
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…
Length-dependent thermal conductivity in suspended single-layer graphene
Xiangfan Xu, Luiz F. C. Pereira, Yu Wang +12
Graphene exhibits extraordinary electronic and mechanical properties, and extremely high thermal conductivity. Being a very stable atomically thick membrane that can be suspended b…
