From Anomalous to Normal: Temperature Dependence of the Band Gap in Two-Dimensional Black Phosphorus
Shenyang Huang, Fanjie Wang, Guowei Zhang +11
The temperature dependence of the band gap is crucial to a semiconductor. Bulk black phosphorus (BP) is known to exhibit an anomalous behavior. Through optical spectroscopy, here w…
Stacking sequence determines Raman intensities of observed interlayer shear modes in 2D layered materials - A general bond polarizability model
Xin Luo, Chunxiao Cong, Xin Lu +3
2D layered materials have recently attracted tremendous interest due to their fascinating properties and potential applications. The interlayer interactions are much weaker than th…
Silane-Catalyzed Fast Growth of Large Single-Crystalline Graphene on Hexagonal Boron Nitride
Shujie Tang, Haomin Wang, Hui Shan Wang +12
The direct growth of high-quality, large single-crystalline domains of graphene on a dielectric substrate is of vital importance for applications in electronics and optoelectronics…
Synthesis and optical properties of large-scale single-crystalline two-dimensional semiconductor WS2 monolayer from chemical vapor deposition
Chunxiao Cong, Jingzhi Shang, Xing Wu +5
Two-dimensional (2D) transition metal dichalcogenides (TMDs), especially MoS2 and WS2 recently attract extensive attentions due to their rich physics and great potential applicatio…
Direct Observation of Inner and Outer G' Band Double-resonance Raman Scattering in Free Standing Graphene
Zhiqiang Luo, Chunxiao Cong, Jun Zhang +2
In contrary to the widely reported single and symmetric peak feature of G' (or 2D) band in Raman spectrum of graphene, we herein report the observation of splitting in G' band in f…
Second-order Overtone and Combinational Raman Modes of Graphene Layers in the Range of 1690 cm-1 to 2150 cm-1
Chunxiao Cong, Ting Yu, Riichiro Saito
Though graphene has been intensively studied by Raman spectroscopy, in this letter, we report a study of second-order overtone and combinational Raman modes in an unexplored range…
