title: Unique photoemission from single-layer graphene on a SiO2 layer by a substrate charging effect.
abstract: Single-layer graphene (SLG) shows an anomalously large surface charging effect during scanning photoelectron microscopy (SPEM), which is distinguished from bi-layer graphene (BLG). The different behaviour is believed due to a different screening effect for SLG and BLG.
