A novel activation method for a B dopant implanted in a Si substrate using a soft X-ray undulator was examined. As the photon energy of the irradiated soft X-ray approached the energy of the core level of Si 2p, the activation ratio increased. The...

Coulomb blockade/staircase phenomena of deoxyribonucleic acid (DNA) molecule have been observed so far. Here, we show a non-Coulomb blockade/staircase phenomenon of holes in a mesoscopic scale lambda-DNA, which serves as a channel on SiO2/Si struc...

Effect of atomic hydrogen annealing (AHA) on graphene oxide (GO) was investigated. In AHA, the high-density atomic hydrogen is generated on heated tungsten (W) surface by catalytic cracking reaction. From X-ray photoelectron spectra, GO films were...

The energy loss of solar cell due to the recombination of holes and electrons which are excited by the incident solar beam is approximately 20% of all the loss-mechanisms. We simulated the solar cell with Metal-Insulator-Semiconductor(MIS) structu...
