Title :
    Graphene Devices: from Transistor to Barristor
Abstract : 
 Graphene has been attracting many intentions for a post-Si material due to its high mobility. Until last year, applications for the graphene transistors are limited to RF transistors which do not have to be turned off during the operation, since its band structure keeps from turning-off the devices. New device structures have been proposed to solve the issue: graphene barristor [1] and graphene tunneling transistor [2]. Both structures have hetero junction between graphene and semiconductor or insulator. In this talk, the research on graphene transistors will be reviewed towards RF (Radio Frequency) applications [3] and the research on graphene barristor or tunneling transistor will be reviewed towards logic applications. Finally, discussed are their potentials and limits as the next generation devices.
