RESEARCH

We have experimentally studied mesoscopic physics, mainly related to superconductivity, by using semiconductor nanofabrication techniques and low-temperature electronic transport measurement techniques. Our research topics in the past include Kosterlitz-Thouless-Brezinski transition of charges in small tunnel junctions networks, Fluxoid quantization in mesoscopic superconducting rings, and novel vortex states in mesoscopic superconductors.

Recently, we are mainly dealing with Cooper-pair and spin transport in graphene. Graphene is a honeycomb lattice of carbon atoms, which was discovered in 2004. Electrons in graphene behave as Dirac fermions. We are interested in observing unusual "relativistic effects", which never been observed in conventional metals.
