Neutrality point of graphene with coplanar charged impurities
M. M. Fogler
The ground-state and the transport properties of graphene subject to the potential of in-plane charged impurities are studied. The screening of the impurity potential is shown to b…
Determination of the electronic structure of bilayer graphene from infrared spectroscopy results
L. M. Zhang, Z. Q. Li, D. N. Basov +3
We present an experimental study of the infrared conductivity, transmission, and reflection of a gated bilayer graphene and their theoretical analysis within the Slonczewski-Weiss-…
Biexcitons in two-dimensional systems with spatially separated electrons and holes
A. D. Meyertholen, M. M. Fogler
The binding energy and wavefunctions of two-dimensional indirect biexcitons are studied analytically and numerically. It is proven that stable biexcitons exist only when the distan…
Band structure asymmetry of bilayer graphene revealed by infrared spectroscopy
Z. Q. Li, E. A. Henriksen, Z. Jiang +5
We report on infrared spectroscopy of bilayer graphene integrated in gated structures. We observed a significant asymmetry in the optical conductivity upon electrostatic doping of…
Pseudomagnetic fields and ballistic transport in a suspended graphene sheet
M. M. Fogler, F. Guinea, M. I. Katsnelson
We study a suspended graphene sheet subject to the electric field of a gate underneath. We compute the elastic deformation of the sheet and the corresponding effective gauge field,…
Effect of spatial resolution on the estimates of the coherence length of excitons in quantum wells
M. M. Fogler, Sen Yang, A. T. Hammack +2
We evaluate the effect of diffraction-limited resolution of the optical system on the estimates of the coherence length of 2D excitons deduced from the interferometric study of the…
