Bosonic field theory of tunable edge magnetism in graphene
Manuel J. Schmidt
A bosonic field theory is derived for the tunable edge magnetism at graphene zigzag edges. The derivation starts from an effective fermionic theory for the interacting graphene edg…
Exact diagonalization study of the tunable edge magnetism in graphene
David J. Luitz, Fakher F. Assaad, Manuel J. Schmidt
The tunable magnetism at graphene edges with lengths of up to 48 unit cells is analyzed by an exact diagonalization technique. For this we use a generalized interacting one-dimensi…
Intrinsic and extrinsic corrugation of monolayer graphene deposited on SiO2
V. Geringer, M. Liebmann, T. Echtermeyer +5
Using scanning tunneling microscopy (STM) in ultra high vacuum and atomic force microscopy, we investigate the corrugation of graphene flakes deposited by exfoliation on a Si/SiO2…
Magnetization-Switched Metal-Insulator Transition in a (Ga,Mn)As Tunnel Device
K. Pappert, M. J. Schmidt, S. Hümpfner +6
We observe the occurrence of an Efros-Shklovskii gap in (Ga,Mn)As based tunnel junctions. The occurrence of the gap is controlled by the extent of the hole wave-function on the Mn…
