    The electronic transport is studied for a carbon nanotube quantum dot with one ferromagnetic and one superconducting lead. We observe a gap in the conductance which is consistent with the energy gap of a superconductor. For bias voltages well above this gap, we observe spin-diode behavior....

    A new visible light response photocatalyst has been developed for H2 evolution from methanol solution by elemental doping. With lanthanum and cobalt dopants, the photoabsorption edge of NaNbO3 was effectively shifted to the visible light region. It is also found that the photoabsorption edge is...

    The energy spectra of a Thue-Morse superlattice based on monolayer graphene containing a band gap are studied. The lattice consists of rectangular barriers located along the x axis. It is proposed that aperiodic Thue-Morse modulation be produced by a difference in the gap width in different...
