Anomalously Strong 2D Band Intensity in Twisted Bilayer Graphene: Raman Evidence for Doubly Degenerate Dirac Band
Yanan Wang, Zhihua Su, Wei Wu +8
We report the observation of anomalously strong 2D band in twisted bilayer graphene (tBLG) with large rotation angles under 638-nm and 532-nm visible laser excitation. The 2D band…
High mobility and high on/off ratio field-effect transistors based on chemical vapor deposited single-crystal MoS2 grains
Wei Wu, Debtanu De, Su-Chi Chang +4
We report field-effect transistors (FETs) with single-crystal molybdenum disulfide (MoS2) channels synthesized by chemical vapor deposition (CVD). For a bilayer MoS2 FET, the mobil…
Twisted Bilayer Graphene Superlattices
Yanan Wang, Zhihua Su, Wei Wu +14
Twisted bilayer graphene (tBLG) provides us with a large rotational freedom to explore new physics and novel device applications, but many of its basic properties remain unresolved…
Growth from Below: Bilayer Graphene on Copper by Chemical Vapor Deposition
Shu Nie, Wei Wu, Shirui Xing +4
We evaluate how a second graphene layer forms and grows on Cu foils during chemical vapor deposition (CVD). Low-energy electron diffraction and microscopy is used to reveal that th…
Control and Characterization of Individual Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Qingkai Yu, Luis A. Jauregui, Wei Wu +14
The strong interest in graphene has motivated the scalable production of high quality graphene and graphene devices. Since large-scale graphene films synthesized to date are typica…
Room-temperature Tunable Fano Resonance by Chemical Doping in Few-layer Graphene Synthesized by Chemical Vapor Deposition
Zhihong Liu, Xiaoxiang Lu, Peng Peng +4
A Fano-like phonon resonance is observed in few-layer (~3) graphene at room temperature using infrared Fourier transform spectroscopy. This Fano resonance is the manifestation of a…
