Broadband graphene terahertz modulators enabled by intraband transitions
Berardi Sensale-Rodriguez,Rusen Yan,Michelle M. Kelly,Tian Fang,Kristof Tahy,Wan Sik Hwang,Debdeep Jena,Lei Liu,Huili Grace Xing +8 more
TL;DR: It is demonstrated that exceptionally efficient broadband modulation of terahertz waves at room temperature can be realized using graphene with extremely low intrinsic signal attenuation, which is also the first demonstrated graphene-based device enabled solely by intraband transitions.
Journal ArticleDOI
Exciton dynamics in suspended monolayer and few-layer MoS₂ 2D crystals
Hongyan Shi,Rusen Yan,Simone Bertolazzi,Jacopo Brivio,Bo Gao,Andras Kis,Debdeep Jena,Huili Grace Xing,Libai Huang +8 more
TL;DR: Fast trapping of excitons by surface trap states was observed in monolayer and few-layer structures, pointing to the importance of controlling surface properties in atomically thin crystals such as MoS₂ along with controlling their dimensions.
Journal ArticleDOI
Thermal Conductivity of Monolayer Molybdenum Disulfide Obtained from Temperature-Dependent Raman Spectroscopy
Rusen Yan,Jeffrey R. Simpson,Simone Bertolazzi,Jacopo Brivio,Michael Watson,Xufei Wu,Andras Kis,Tengfei Luo,Angela R. Hight Walker,Huili Grace Xing +9 more
TL;DR: In this paper, the temperature-dependent Raman spectra of exfoliated, monolayer molybdenum disulfide (MoS2) in the range of 100-320 K were analyzed.
Journal ArticleDOI
Esaki Diodes in van der Waals Heterojunctions with Broken-Gap Energy Band Alignment
Rusen Yan,Rusen Yan,Sara Fathipour,Yimo Han,Bo Song,Bo Song,Shudong Xiao,Mingda Li,Nan Ma,Vladimir Protasenko,David A. Muller,Debdeep Jena,Debdeep Jena,Huili Grace Xing,Huili Grace Xing +14 more
TL;DR: The first demonstration of an important building block in vdW solids: room temperature Esaki tunnel diodes is presented and the broken-gap band alignment is confirmed by the junction photoresponse, and the phosphorus double planes in a single layer of BP are resolved in transmission electron microscopy (TEM) for the first time.
Journal ArticleDOI
Transistors with Chemically Synthesized Layered Semiconductor WS2 Exhibiting 105 Room Temperature Modulation and Ambipolar Behavior
Wan Sik Hwang,Maja Remškar,Rusen Yan,Vladimir Protasenko,Kristof Tahy,Soo Doo Chae,Pei Zhao,Aniruddha Konar,Huili,Xing,Alan Seabaugh,Debdeep Jena +11 more
TL;DR: In this paper, the authors reported the realization of field effect transistors (FETs) made with chemically synthesized layered two dimensional (2D) crystal semiconductor WS2, which demonstrated ambipolar behavior and a high (~105x) on/off current ratio at room temperature with current saturation.
