* ABSTRACT

Mono- and bilayer graphene are novel two-dimensional electronic systems
in which the effects of electronic band structure, including the
formation of unconventional Landau levels, are explicitly demonstrated.
We developed a unique lithography-free, all-dry process for graphene
device fabrication and performed electrical transport and tunneling
measurements on monolayer graphene, bilayer graphene, and their hybrids.
Our work on the latter system consisting a continuous graphene sheet
with a mono- and bilayer portion and an interface between them will be
the main focus of this presentation. We found anomalous features in
quantum oscillation of these hybrids, suggesting the existence of novel
interface states.
