The focusing of electron flow in a bipolar Graphene ribbon with different chiralities
focusing of electron flow different chiralities
2010/11/22
The focusing of electron flow in a symmetric p-n junction (PNJ) of graphene ribbon with different chiralities is studied. Considering the PNJ with the sharp interface, in a armchair ribbon, the electr...
The parity of specular Andreev reflection under mirror operation in zigzag graphene ribbon
parity of specular Andreev reflection mirror operation
2010/11/25
It is known that the parity of reflection amplitude can either be even or odd under the mirror
operation. Up to now, all the parities of reflection amplitude in the one-mode energy region are even un...
