(author), Klein, T. (author), Bustarret, E. (author)We report a study of the relaxation time of the restoration of the resistive superconducting state in single crystalline boron-doped diamond using amplitude-modulated absorption of (sub-)THz radiation (AMAR). The films grown on an insulating diamond substrate have a low carrier density of about 2.5×1021cm?3 and a critical temperature of about 2K...journal article 2016

Oostinga, J.B. (author), Sacépé, B. (author), Craciun, M.F. (author), Morpurgo, A.F. (author)We investigate magnetotransport through graphene nanoribbons as a function of gate and bias voltage, and temperature. We find that a magnetic field systematically leads to an increase in the conductance on a scale of a few tesla. This phenomenon is accompanied by a decrease in the energy scales associated to charging effects, and to hopping...journal article 2010
