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.

基于这一创意，利用一种新的温度控制工艺，实现了金属薄膜与衬底之间的应力梯度控制，以及金属原子的扩散速度与表面氧化层生长速度的匹配，从而成功地发明了超高质量的单晶金属纳米线。利用研制的微波原子力显微镜和霍尔效应四点探针，对金属纳米线的电导率、载流子密度和迁移率进行了实验分析，建立了基于纳米线表面热辐射效应的电子传递机制。基于本研究的成功，有可能突破纳米传感器和纳米器件的商业可行性难题，并有望为绿色和生命创新做出贡献。
