| 1 | WSe2 2D p-type semiconductor-based electronic devices for information technology:Design,preparation,and applications显示文摘The pioneering exfoliation of monolayer tungsten diselenide has greatly inspired researchers toward semiconducting applications.WSe2 belongs to a family of transition-metal dichalcogenides.Similar to graphene,WSe2 and analogous dichalcogenides have layered structures with weak van der Waals interactions between two adjacent layers.First,the readers are presented with the fundamentals of WSe2,such as types,morphologies,and properties.Here,we report the characterization principles and practices such as microscopy,spectroscopy,and diffraction.Second,the methods for obtaining high-quality WSe2,such as exfoliation,hydrothermal and chemical vapor deposition,are briefly listed.With advantages of light weight,flexibility,and high quantum efficiency,2D materials may have a niche in optoelectronics as building blocks in p-n junctions.Therefore,we introduce a state-of-the-art demonstration of heterostructure devices employing the p-type WSe2 semiconductor.The device architectures include field-effect transistors,photodetectors,gas sensors,and photovoltaic solar cells.Due to its unique electronic,optical,and energy band properties,WSe2 has been increasingly investigated due to the conductivity of the p-type charge carrier upon palladium contact.Eventually,the dynamic research on WSe2 and van der Waals heterostructures is summarized to arouse the passion of the 2D research community. | Qilin Cheng Jinbo Pang Dehui Sun Jingang Wang Shu Zhang Fan Liu Yuke Chen Ruiqi Yang Na Liang Xiheng Lu Yanchen Ji Jian Wang Congcong Zhang Yuanhua Sang Hong Liu Weijia Zhou | 2020 | InfoMat2020，2，4： | 5 |
| 2 | Multiscale computational understanding and growth of 2D materials:a review显示文摘The successful discovery and isolation of graphene in 2004,and the subsequent synthesis of layered semiconductors and heterostructures beyond graphene have led to the exploding field of two-dimensional(2D)materials that explore their growth,new atomic-scale physics,and potential device applications.This review aims to provide an overview of theoretical,computational,and machine learning methods and tools at multiple length and time scales,and discuss how they can be utilized to assist/guide the design and synthesis of 2D materials beyond graphene. | Kasra Momeni Yanzhou Ji Yuanxi Wang Shiddartha Paul Sara Neshani Dundar E.Yilmaz Yun Kyung Shin Difan Zhang Jin-Wu Jiang Harold S.Park Susan Sinnott Adri van Duin Vincent Crespi Long-Qing Chen | 2020 | npj Computational Materials2020，，1： | 4 |
