Abstract

We report two-dimensional (2D) electron and hole gases induced at the surface of graphite by the electric field effect. The 2D gases reside within a few near-surface atomic layers and exhibit mobilities up to 15000 and 60000cm2/Vs at room and liquid-helium temperatures, respectively. The mobilities imply ballistic transport on μm scale. Pronounced Shubnikov-de Haas oscillations reveal the existence of two types of charge carries in both electron and hole gases. © 2005 The American Physical Society.
