✦ Synopsis

Temperature dependence of photoconductivity has been investigated for single-wall carbon nanotube films at 0.7 eV. In order to clarify the effect of atmosphere on photoconductivity, measurements have been performed under helium and nitrogen gas flow in the temperature range from 10 K to room temperature (RT) and from 100 K to RT, respectively. Photoconductive response monotonously increases with a decrease in temperature and tends to saturate around 10 K. No clear difference in photoconductive response under different atmosphere was observed. We discuss the mechanism of photoconductivity at 0.7 eV.

This study is devoted to the angular distribution of protons of the energy of 1 GeV channeled in a bent short rope of (10, 10) single-wall carbon nanotubes as a function of the bending angle. The rope length was chosen to be 7 lm, corresponding to the reduced rope length associated with the transver
