Electronic structure of heavily-doped graphene: the role of foreign atom states

open access: yes, 2007
Using density functional theory calculations we investigate the electronic structure of graphene doped by deposition of foreign atoms. We demonstrate that, as the charge transfer to the graphene layer increases, the band structure of the pristine ...

Non-linearity Induced Weak Instrumentation [PDF]

open access: yes
In regressions involving integrable functions we examine the limit properties of IV estimators that utilise integrable transformations of lagged regressors as instruments. The regressors can be either I(0) or I(1) processes.

A scalar hyperbolic equation with GR-type non-linearity

open access: yes, 2003
We study a scalar hyperbolic partial differential equation with non-linear terms similar to those of the equations of general relativity. The equation has a number of non-trivial analytical solutions whose existence rely on a delicate balance between ...
