We investigate the energy relaxation of hot carriers in a CVD-grown graphene device with a top h-BN layer by driving the devices into the nonequilibrium regime. By using the magnetic field dependent conductance fluctuations of our graphene device as

Fullerenes became a new member of carbon allotropes in addition to diamond and graphite after the discovery of C60 (carbon 60) by Kroto et al. in 1985. The model of C60 was first proposed by Osawa in 1970. C60 is a hollow spherical molecule composed

We have performed transport measurements on a multi-layer graphene device fabricated by conventional mechanical exfoliation. By using the zero-field resistance of our graphene device as a self-thermometer, we are able to determine the effective Dirac

A flake of monolayer graphene was sandwiched between boron nitride sheets. Temperature dependent Shubnikov–de Haas measurements were performed to access how this technique influences the electronic properties of the graphene sample. The maximum mob

We have fabricated a high mobility device, composed of a monolayer graphene flake sandwiched between two sheets of hexagonal boron nitride. Conductance fluctuations as functions of a back gate voltage and magnetic field were obtained to check for erg
