Journal Article
Charged Impurity Scattering in Bilayer Graphene
Journal ArticleDOI
Atomic Structure of Graphene on SiO2
TL;DR: In this paper, the authors employed scanning probe microscopy to reveal atomic structures and nanoscale morphology of graphene-based electronic devices (i.e., a graphene sheet supported by an insulating silicon dioxide substrate) for the first time.
Journal ArticleDOI
Raman Signatures of Broken Inversion Symmetry and In‐Plane Anisotropy in Type‐II Weyl Semimetal Candidate TaIrTe4
Yinan Liu,Qiangqiang Gu,Yu Peng,Shaomian Qi,Na Zhang,Yinong Zhang,Xiumei Ma,Rui Zhu,Lianming Tong,Ji Feng,Ji Feng,Zheng Liu,Jian-Hao Chen +12 more
TL;DR: An unambiguous identification of the broken inversion symmetry in TaIrTe4 is established using angle-resolved polarized Raman spectroscopy, which could be extended to the fast identification and characterization of other type-II Weyl fermions candidates.
Journal ArticleDOI
Robust edge photocurrent response on layered type II Weyl semimetal WTe2.
Qinsheng Wang,Jingchuan Zheng,Yuan He,Jin Cao,Xin Liu,Maoyuan Wang,Junchao Ma,Jiawei Lai,Hong Lu,Shuang Jia,Dayu Yan,Youguo Shi,Junxi Duan,Junfeng Han,Wende Xiao,Jian-Hao Chen,Kai Sun,Yugui Yao,Dong Sun +18 more
TL;DR: In this article, robust photocurrent generation at the edge of Td-WTe2, a type-II Weyl semimetal, due to crystalline-symmetry breaking along certain crystal fracture directions and possibly enhanced by robust fermi-arc type surface states was demonstrated.
Journal ArticleDOI
Uncovering the dominant scatterer in graphene sheets on SiO 2
Jyoti Katoch,Jian-Hao Chen,Ryuichi Tsuchikawa,Christian W. Smith,Eduardo R. Mucciolo,Masa Ishigami +5 more
TL;DR: In this paper, the authors measured the impact of hydrogen adsorption on the electronic transport properties of graphene sheets as a function of hydrogen coverage and initial, pre-hydrogenation field effect mobility.
