Direct observation of dynamic charge stripes in La2-xSrxNiO4
S. Anissimova, D. Parshall, G. D. Gu +8
The insulator-to-metal transition continues to be a challenging subject, especially when electronic correlations are strong. In layered compounds, such as La2-xSrxNiO4 and La2-xBax…
Temperature dependence of low-energy phonons in magnetic nonsuperconducting TbNi2B2C
S. Anissimova, A. Kreyssig, O. Stockert +2
We report temperature dependence of low-energy phonons in magnetic nonsuperconducting TbNi2B2C single crystals measured by inelastic neutron scattering. We observed a low-temperatu…
Graphene as a transparent conductive support for studying biological molecules by transmission electron microscopy
R. R. Nair, P. Blake, J. R. Blake +8
We demonstrate the application of graphene as a support for imaging individual biological molecules in transmission electron microscope (TEM). A simple procedure to produce free-st…
Spectroscopic ellipsometry of graphene and an exciton-shifted van Hove peak in absorption
V. G. Kravets, A. N. Grigorenko, R. R. Nair +4
We demonstrate that optical transparency of any two-dimensional system with a symmetric electronic spectrum is governed by the fine structure constant and suggest a simple formula…
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…
Flow diagram of the metal-insulator transition in two dimensions
S. Anissimova, S. V. Kravchenko, A. Punnoose +2
The discovery of the metal-insulator transition (MIT) in two-dimensional (2D) electron systems challenged the veracity of one of the most influential conjectures in the physics of…
