One-step exfoliation method for plasmonic activation of large-area 2D crystals
Qiang Fu, Jia-Qi Dai, Xin-Yu Huang +16
Advanced exfoliation techniques are crucial for exploring the intrinsic properties and applications of 2D materials. Though the recently discovered Au-enhanced exfoliation techniqu…
Direct Visualization of Irreducible Ferrielectricity in Crystals
Kai Du, Lei Guo, Jin Peng +12
In solids, charge polarity can one-to-one correspond to spin polarity phenomenologically, e.g. ferroelectricity/ferromagnetism, antiferroelectricity/antiferromagnetism, and even di…
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…
On resonant scatterers as a factor limiting carrier mobility in graphene
Z. H. Ni, L. A. Ponomarenko, R. R. Nair +8
We show that graphene deposited on a substrate has a non-negligible density of atomic scale defects. This is evidenced by a previously unnoticed D peak in the Raman spectra with in…
Fabrication of graphene nanodisk arrays using nanosphere lithography
C. X. Cong, T. Yu, Z. H. Ni +3
Ordered graphene nanodisk arrays have been successfully fabricated by combining nanosphere lithography (NSL) and reactive ion etching (RIE) processes. The dimension of graphene nan…
Probing charged impurities in suspended graphene using Raman spectroscopy
Zhen Hua Ni, Ting Yu, Zhi Qiang Luo +6
Charged impurity (CI) scattering is one of the dominant factors that affect the carrier mobility in graphene. In this paper, we use Raman spectroscopy to probe the charged impuriti…
