| Research Abstract |
Based on a creative idea, the controlling of the stress gradient between the metal film and substrate, and the matching between the diffusion velocity of metal atoms and the growth speed of surface oxide layer, were realized utilizing a new temperature control process, thereby the invention of ultra-high quality single crystal metal nanowires was succeed. Moreover, using the developed original microwave atomic-force microscope and developing a hall-effect four-point-probe measurement, the experimental analysis of conductivity, carrier density and mobility of metal nanowires was carried out and a new electron transport mechanism was built up based on the surface thermal radiation effect of nanowires. Based on the success of this research, it may possible to break through the difficulty of the commercial viability of nano-sensors and nano-devices, and it is expected to have a contribution to green and life Innovations.
