Journal ArticleDOI
High-speed graphene transistors with a self-aligned nanowire gate
Lei Liao,Yung-Chen Lin,Mingqiang Bao,Rui Cheng,Jingwei Bai,Yuan Liu,Yongquan Qu,Kang L. Wang,Yu Huang,Xiangfeng Duan +9 more
TL;DR: On-chip microwave measurements demonstrate that the self-aligned graphene transistors have a high intrinsic cut-off (transit) frequency of fT = 100–300 GHz, with the extrinsic fT largely limited by parasitic pad capacitance.
Journal ArticleDOI
Approaching the Schottky-Mott limit in van der Waals metal-semiconductor junctions.
Yuan Liu,Yuan Liu,Jian Guo,Enbo Zhu,Lei Liao,Sung-Joon Lee,Mengning Ding,Imran Shakir,Vincent Gambin,Yu Huang,Xiangfeng Duan +10 more
TL;DR: The creation of van der Waals metal–semiconductor junctions is reported, in which atomically flat metal thin films are laminated onto two-dimensional semiconductors without direct chemical bonding, creating an interface that is essentially free from chemical disorder and Fermi-level pinning.
Journal ArticleDOI
Graphene: An Emerging Electronic Material
Nathan O. Weiss,Hailong Zhou,Lei Liao,Yuan Liu,Shan Jiang,Yu Huang,Yu Huang,Xiangfeng Duan,Xiangfeng Duan +8 more
TL;DR: The versatility of graphene-based devices goes beyond conventional transistor circuits and includes flexible and transparent electronics, optoelectronics, sensors, electromechanical systems, and energy technologies.
Journal ArticleDOI
Plasmon resonance enhanced multicolour photodetection by graphene
Yuan Liu,Rui Cheng,Lei Liao,Hailong Zhou,Jingwei Bai,Gang Liu,Lixin Liu,Yu Huang,Xiangfeng Duan +8 more
TL;DR: It is shown that metallic plasmonic nanostructures can be integrated with graphene photodetectors to greatly enhance the photocurrent and external quantum efficiency by up to 1,500%.
Journal ArticleDOI
Ultrasensitive and Broadband MoS2 Photodetector Driven by Ferroelectrics
Xudong Wang,Xudong Wang,Peng Wang,Jianlu Wang,Weida Hu,Xiaohao Zhou,Nan Guo,Hai Huang,Shuo Sun,Hong Shen,Tie Lin,Minghua Tang,Lei Liao,Anquan Jiang,Jinglan Sun,Xiangjian Meng,Xiaoshuang Chen,Wei Lu,Junhao Chu +18 more
TL;DR: A few-layer MoS2 photodetector driven by poly(vinylidene fluoride-trifluoroethylene) ferroelectrics is achieved, tuned by the ultrahigh electrostatic field from the ferroelectric polarization.
