Revealing the Origin of Luminescence Center in 0D Cs4PbBr6 Perovskite
Zhaojun Qin, Shenyu Dai, Viktor G. Hadjiev +13
Zero dimensional perovskite Cs4PbBr6 has attracted considerable attention recently not only because of its highly efficient green photoluminescence (PL), but also its two highly de…
Bright Luminescent Surface States on the Edges of Wide-bandgap Two-dimensional Lead Halide Perovskite
Yanan Wang, Chong Wang, Xinghua Su +9
Three-dimensional lead halide perovskites have surprised people for their defect-tolerant electronic and optical properties, two-dimensional lead halide layered structures exhibit…
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…
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…
Large-scale Graphitic Thin Films Synthesized on Ni and Transferred to Insulators: Structural and Electronic Properties
Helin Cao, Qingkai Yu, Robert Colby +11
We present a comprehensive study of the structural and electronic properties of ultrathin films containing graphene layers synthesized by chemical vapor deposition (CVD) based surf…
Graphene Segregated on Ni surfaces and Transferred to Insulators
Qingkai Yu, Jie Lian, Sujitra Siriponglert +3
We report an approach to synthesize high quality graphene by surface segregation and substrate transfer. Graphene was segregated from Ni surface under the ambient pressure by disso…
