Journal ArticleDOI
The Role of Surface Oxygen in the Growth of Large Single-Crystal Graphene on Copper
Yufeng Hao,M. S. Bharathi,Lei Wang,Yuanyue Liu,Hua Chen,Shu Nie,Xiaohan Wang,Harry Chou,Cheng Tan,Babak Fallahazad,H. Ramanarayan,Carl W. Magnuson,Emanuel Tutuc,Boris I. Yakobson,Kevin F. McCarty,Yong-Wei Zhang,Philip Kim,James Hone,Luigi Colombo,Rodney S. Ruoff +19 more
TL;DR: It was found that the presence of surface oxygen could limit the number of nucleation sites and allowed centimeter-scale domains to grow through a diffusion-limited mechanism, and the electrical conductivity of the graphene was comparable to that of exfoliated graphene.
Journal ArticleDOI
Correlated electronic phases in twisted bilayer transition metal dichalcogenides
Lei Wang,Lei Wang,En-Min Shih,Augusto Ghiotto,Lede Xian,Daniel Rhodes,Cheng Tan,Martin Claassen,Dante M. Kennes,Dante M. Kennes,Yusong Bai,Bumho Kim,Kenji Watanabe,Takashi Taniguchi,Xiaoyang Zhu,James Hone,Angel Rubio,Angel Rubio,Abhay Pasupathy,Cory Dean +19 more
TL;DR: The observation of tunable collective phases in a simple band, which hosts only two holes per unit cell at full filling, establishes twisted bilayer transition metal dichalcogenides as an ideal platform to study correlated physics in two dimensions on a triangular lattice.
Journal ArticleDOI
Tuning quantum nonlocal effects in graphene plasmonics
Mark B. Lundeberg,Yuanda Gao,Reza Asgari,Cheng Tan,Ben Van Duppen,Marta Autore,Pablo Alonso-González,Achim Woessner,Kenji Watanabe,Takashi Taniguchi,Rainer Hillenbrand,James Hone,Marco Polini,Frank H. L. Koppens,Frank H. L. Koppens +14 more
TL;DR: Graphene plasmons are used, propagating at extremely slow velocities close to the electron Fermi velocity, to probe the nonlocal response of the graphene electron liquid, and a parameter-free match with the full quantum description of the massless Dirac electron gas is revealed.
Journal ArticleDOI
Reduced Graphene Oxide/Copper Nanowire Hybrid Films as High-Performance Transparent Electrodes
Iskandar Kholmanov,Iskandar Kholmanov,Sergio H. Domingues,Sergio H. Domingues,Harry Chou,Xiaohan Wang,Cheng Tan,Jinyoung Kim,Huifeng Li,Richard D. Piner,Aldo J. G. Zarbin,Rodney S. Ruoff +11 more
TL;DR: Compared to Cu NW films, the RG-O/Cu NW hybrid films have improved electrical conductivity, oxidation resistance, substrate adhesion, and stability in harsh environments.
Journal ArticleDOI
Pressure-dependent optical and vibrational properties of monolayer molybdenum disulfide.
Avinash P. Nayak,Tribhuwan Pandey,Damien Voiry,Jin Liu,Samuel T. Moran,Ankit Sharma,Cheng Tan,Chang-Hsiao Chen,Lain-Jong Li,Manish Chhowalla,Jung-Fu Lin,Abhishek K. Singh,Deji Akinwande +12 more
TL;DR: The results present an important advance toward controlling the band structure and optoelectronic properties of monolayer MoS2 via pressure, which has vital implications for enhanced device applications.
