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…
Two-dimensional Quasi-Freestanding Molecular Crystals for High-Performance Organic Field-Effect Transistors
Daowei He, Yuhan Zhang, Qisheng Wu +18
Two-dimensional atomic crystals are extensively studied in recent years due to their exciting physics and device applications. However, a molecular counterpart, with scalable proce…
Strong Photoluminescence Enhancement of MoS2 through Defect Engineering and Oxygen Bonding
Haiyan Nan, Zilu Wang, Wenhui Wang +9
We report on a strong photoluminescence (PL) enhancement of monolayer MoS2 through defect engineering and oxygen bonding. Micro- PL and Raman images clearly reveal that the PL enha…
Probing Carrier Transport and Structure-property Relationship of Highly Ordered Organic Semiconductors at Two-dimensional Limit
Yuhan Zhang, Jingsi Qiao, Si Gao +14
One of the basic assumptions in organic field-effect transistors, the most fundamental device unit in organic electronics, is that charge transport occurs two-dimensionally in the…
Integrating high-quality dielectrics with one-nanometer equivalent oxide thickness on two-dimensional electronic devices
Weisheng Li, Jian Zhou, Songhua Cai +21
Two-dimensional (2D) semiconductors are widely recognized as attractive channel materials for low-power electronics. However, an unresolved challenge is the integration of high-qua…
Unveiling the Structural Origin of the High Carrier Mobility of a Molecular Monolayer on Boron Nitride
Rui Xu, Daowei He, Yuhan Zhang +10
Very recently, it was demonstrated that the carrier mobility of a molecular monolayer dioctylbenzothienobenzothiophene (C8-BTBT) on boron nitride can reach 10 cm2/Vs, the highest a…
