Journal ArticleDOI
Van der Waals heterostructures and devices
TL;DR: In this paper, the authors review the recent progress and challenges of 2D van der Waals interactions and offer a perspective on the exploration of 2DLM-based vdWHs for future application in electronics and optoelectronics.
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
Highly efficient gate-tunable photocurrent generation in vertical heterostructures of layered materials
TL;DR: It is demonstrated that the amplitude and polarity of the photocurrent in the gated vertical heterostructures can be readily modulated by the electric field of an external gate to achieve a maximum external quantum efficiency of 55% and internal quantum efficiency up to 85%.
Journal ArticleDOI
Flexible solid-state supercapacitors based on three-dimensional graphene hydrogel films.
TL;DR: The exploration of a three-dimensional (3D) graphene hydrogel for the fabrication of high-performance solid-state flexible supercapacitors demonstrates the exciting potential of 3D graphene macrostructures for high- performance flexible energy storage devices.
