Experimental observation of the quantum Hall effect and Berry's phase in graphene

Large-scale pattern growth of graphene films for stretchable transparent electrodes

Ultrahigh electron mobility in suspended graphene

Energy Band-Gap Engineering of Graphene Nanoribbons

We investigate electronic transport in lithographically patterned graphene ribbon structures where the lateral confinement of charge carriers creates an energy gap near the char...

Graphene based heterostructures

Thermal Transport Measurements of Individual Multiwalled Nanotubes

The thermal conductivity and thermoelectric power of a single carbon nanotube were measured using a microfabricated suspended device. The observed thermal conductivity is more t...

Measurement of Scattering Rate and Minimum Conductivity in Graphene

The conductivity of graphene samples with various levels of disorder is investigated for a set of specimens with mobility in the range of 1-20x10(3) cm2/V sec. Comparing the exp...

High-resolution scanning tunneling microscopy imaging of mesoscopic graphene sheets on an insulating surface

We present scanning tunneling microscopy (STM) images of single-layer graphene crystals examined under ultrahigh vacuum conditions. The samples, with lateral dimensions on the m...

One-Dimensional Electrical Contact to a Two-Dimensional Material

Better Contact Along the Edge Electrical contact to graphene is normally done with metal contacts on its flat face, where there are few strong bonding sites for the metal. Wang ...
