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…
Synthetic Graphene Grown by Chemical Vapor Deposition on Copper Foils
Ting Fung Chung, Tian Shen, Helin Cao +5
The discovery of graphene, a single layer of covalently bonded carbon atoms, has attracted intense interests. Initial studies using mechanically exfoliated graphene unveiled its re…
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…
Graphene Induced Surface Reconstruction of Cu
Jifa Tian, Helin Cao, Wei Wu +3
An atomic-scale study utilizing scanning tunneling microscopy (STM) in ultrahigh vacuum (UHV) is performed on large single crystalline graphene grains synthesized on Cu foil by a c…
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…
