Oxidized-monolayer Tunneling Barrier for Strong Fermi-level Depinning in Layered InSe Transistors
Yi-Hsun Chen, Chih-Yi Cheng, Shao-Yu Chen +9
In 2D-semiconductor-based field-effect transistors and optoelectronic devices, metal-semiconductor junctions are one of the crucial factors determining device performance. The Ferm…
High-performance InSe Transistors with Ohmic Contact Enabled by Nonrectifying-barrier-type Indium Electrodes
Yu-Ting Huang, Yi-Hsun Chen, Yi-Ju Ho +10
The electrical contact to two-dimensional (2D)-semiconductor materials are decisive to the electronic performance of 2D-semiconductor field-effect devices (FEDs). The presence of a…
Environment-insensitive and gate-controllable photocurrent enabled by bandgap engineering of MoS2 junctions
Fu-Yu Shih, Yueh-Chun Wu, Yi-Siang Shih +6
Two-dimensional (2D) materials are composed of atomically thin crystals with an enormous surface-to-volume ratio, and their physical properties can be easily subjected to the chang…
Observation of quantum Hall plateau-plateau transition and scaling behavior of the zeroth Landau level in graphene p-n-p junctions

Electrical Detection of Spin Precession in Single Layer Graphene Spin Valves with Transparent Contacts
Wei Han, K. Pi, W. Bao +5
Spin accumulation and spin precession in single-layer graphene are studied by non-local spin valve measurements at room temperature. The dependence of the non-local magnetoresistan…
Electron-Hole Asymmetry of Spin Injection and Transport in Single-Layer Graphene
Wei Han, W. H. Wang, K. Pi +6
Spin-dependent properties of single-layer graphene (SLG) have been studied by non-local spin valve measurements at room temperature. Gate voltage dependence shows that the non-loca…
