Thermal Dynamics of Graphene Edges Investigated by Polarized Raman Spectroscopy
Ya Nan Xu, Da Zhan, Lei Liu +5
In this report, we present Raman spectroscopy investigation of the thermal stability and dynamics of graphene edges. It was found that graphene edges (both armchair and zigzag) are…
Magnetoelectric coupling at the interface of BiFeO3/La0.7Sr0.3MnO3 multilayers
M. J. Calderon, S. Liang, R. Yu +6
Electric-field controlled exchange bias in a heterostructure composed of the ferromagnetic manganite La0.7Sr0.3MO3 and the ferroelectric antiferromagnetic BiFeO3 has recently been…
Composition of fluctuations of different observables
Grzegorz Wilk, Zbigniew Wlodarczyk, Wojciech Wolak
We demonstrate that description of fluctuations observed in multiparticle production processes using Tsallis statistics approach (in which fluctuations are described by the nonexte…
Gold on graphene as a substrate for surface enhanced Raman scattering study
Yingying Wang, Zhenhua Ni, Hailong Hu +5
In this paper, we report our study on gold (Au) films with different thicknesses deposited on single layer graphene (SLG) as surface enhanced Raman scattering (SERS) substrates for…
Quantum electrodynamics in a whispering-gallery microcavity coated with a polymer nanolayer
Yun-Feng Xiao, Chang-Ling Zou, Peng Xue +5
Quasi-transverse-electric and -transverse-magnetic fundamental whispering gallery modes in a polymer-coated silica microtoroid are theoretically investigated and demonstrated to po…
Peak Effect of Flux Pinning in Sc5Ir4Si10 Superconductors
Y. Sun, Z. X. Shi, D. M. Gu +2
Magnetic hysteresis loops (MHLs) have been comparatively measured on both textured and single crystalline Sc5Ir4Si10 superconductors. Critical current densities and flux pinning fo…
