Electron and Hole Photoemission Detection for Band Offset Determination of Tunnel Field-Effect Transistor Heterojunctions
Wei Li, Qin Zhang, R. Bijesh +9
The electrical performance of a tunnel field-effect transistor depends critically on the band offset at their semiconductor heterojunction interface. Historically, it has been diff…
Broad Band Optical Properties of Large Area Monolayer CVD Molybdenum Disulfide
Wei Li, A. Glen Birdwell, Matin Amani +9
Recently emerging large-area single-layer MoS2 grown by chemical vapor deposition has triggered great interest due to its exciting potential for applications in advanced electronic…
Highly reproducible metal/graphene contacts and stable electrical performance by UV-Ozone treatment
Wei Li, Christina A. Hacker, Yiran Liang +4
Resist residue from the device fabrication process is a general and significant source of the metal/graphene contact interface contamination. In this paper, Ultraviolet-Ozone (UVO)…
UV/Ozone treatment to reduce metal-graphene contact resistance
Wei Li, Yiran Liang, Dangmin Yu +10
We report reduced contact resistance of single-layer graphene devices by using ultraviolet ozone (UVO) treatment to modify the metal/graphene contact interface. The devices were fa…
Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide
Rusen Yan, Qin Zhang, Oleg A. Kirillov +10
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collec…
