Manifesting pseudo-spin polarization on the edge of graphene via field
emission image [PDF]
Jingkun Chen, Zhibing Li, Weiliang WangField emission wave function from graphene in magnetic field is obtained. The emission image reveals structure of the Landau levels and depends on the phase difference between two sub-lattices. The emission pattern is sensitive to the edge potential shift that can be controlled via a gate voltage on the edge.View original: http://arxiv.org/abs/1302.5916
