High responsivity phototransistors based on few-layer ReS2 for weak signal detection
Erfu Liu, Mingsheng Long, Junwen Zeng +18
Two-dimensional transition metal dichalcogenides are emerging with tremendous potential in many optoelectronic applications due to their strong light-matter interactions. To fully…
Strong room-temperature blue-violet photoluminescence of multiferroic BaMnF
Shuang Zhou, Yakui Weng, Zhangting Wu +5
BaMnF microsheets have been prepared by hydrothermal method. Strong room-temperature blue-violet photoluminescence has been observed (absolute luminescence quantum yield 67%),…
A van der Waals pn heterojunction with organic/inorganic semiconductors
Daowei He, Yiming Pan, Haiyan Nan +13
van der Waals (vdW) heterojunctions formed by two-dimensional (2D) materials have attracted tremendous attention due to their excellent electrical/optical properties and device app…
High-Performance Monolayer WS2 Field-effect Transistors on High-k Dielectrics
Yang Cui, Run Xin, Zhihao Yu +13
The combination of high-quality Al2O3 dielectric and thiol chemistry passivation can effectively reduce the density of interface traps and Coulomb impurities of WS2, leading to a s…
Raman vibrational spectra of bulk to monolayer ReS2 with lower symmetry
Yanqing Feng, Wei Zhou, Yaojia Wang +10
Lattice structure and symmetry of two-dimensional (2D) layered materials are of key importance to their fundamental mechanical, thermal, electronic and optical properties. Raman sp…
