AFM local oxidation nanolithography of graphene
Lishan Weng, Liyuan Zhang, Yong P. Chen +1
We demonstrate the local oxidation nanopatterning of graphene films by an atomic force microscope. The technique provides a method to form insulating trenches in graphene flakes an…

Anisotropic modification of the effective hole -factor by electrostatic confinement
S. P. Koduvayur, L. P. Rokhinson, D. C. Tsui +2
We investigate effects of lateral confinement on spin splitting of energy levels in 2D hole gases grown on [311] GaAs. We found that lateral confinement enhances anisotropy of spin…

Weak localization in GaMnAs: evidence of impurity band transport
L. P. Rokhinson, Y. Lyanda-Geller, Z. Ge +4
We report the observation of negative magnetoresistance in the ferromagnetic semiconductor GaMnAs at low temperatures ( K) and low magnetic fields ( mT). We attribut…
