Research Abstract

N-type semiconductor oxides with different band gap (TiO_2: 3.0 eV, SnO_2: 3.7 eV) were deposited inside p-type carbon nanotubes (CNTs). It was clarified that the resistance changes of these materials to 1 ppm NO_2 depended on band-gap of oxides corresponded to the magnitude of p-n junction. Besides, the current differentiated by bias voltage was examined for CNTs and SnO_2-CNTs by means of scanning tunneling spectroscopy (STS). As the result, the formation of p-n junction for SnO_2-CNTs was confirmed from the band-gap evaluated from CNTs and SnO_2-CNTs.
