Abstract

Based on the similarity between the chiral nanotube and the classical solenoid, we study chiral transport along the circumferential direction in a carbon nanotube. We calculate the chiral conductivity, representing a circumferential current induced by an electric field along the nanotube axis for various chiralities of carbon nanotubes. We find that the chiral conductivity in a chiral nanotube is in general non zero, and oscillates as a function of the Fermi energy. This oscillating behavior is attributed to the subband structure of the nanotubes and the warping of the Fermi surfaces., Comment: 10 pages, 5 figures

Abstract

Carbene-carbene rearrangement between 1-phenyl-3-diazopropyne and 3-phenyl-3-diazopropyne involves a singlet excited state and a triplet ground state, subsequent to diazo compound photolysis and organic matrix annealing. The medium plays a vital role in the rearrangement during photolysis. The rearrangement mechanism exhibits an energy barrier of less than 67 K.

Abstract

The density of states and conductivity of monolayer graphene are calculated in the presence of long-range scatterers within a self-consistent Born Approximation. The energy region affected strongly by scatterers decreases in proportion to the inverse of the potential range and the minimum conductivity at the Dirac point becomes nonuniversal.
