The research team achieved a large area of ​​nanostructured optical orientation assembly

Huang Xiaoping, associate professor of School of Materials Science and Technology, University of Electronic Science and Technology of China, cooperated with Luo Xianang, a researcher at the Institute of Optics and Electronics of Chinese Academy of Sciences, and Xu Qingyu, a professor of Southeast University, to study the theory and technology of directed laser field evanescent standing wave field orientation assembly in metal nanometer array structure and made important progress. Related results recently published in the "nano-scale" magazine.

It is understood that Huang Xiaoping mainly micro-nano array structure preparation and optical properties. Recently, based on the research results of ultrathin layer-based electrochemical deposition of two-dimensional metal micro-nano array structure, Huang Xiaoping developed the use of laser evanescent standing wave field in the ultra-thin precious metal nanoparticle colloidal solution and Which produce periodic optical field force, and finally realize the directional assembly of a stable nano-array structure.

Subsequently, with the cooperation with Luo Xian just et al., Huang Xiaoping et al. Thoroughly understood the physical mechanism of the light-controlled assembly of the array structure and studied the anisotropic polarization characteristics of the array structure and the electromagnetic enhancement mechanism of the Raman spectrum on the polarized surface. This research has developed a new method for rapid micromachining of large-area metal micro / nano array structure patterns, which can provide theoretical and technical basis for the application of surface-enhanced Raman biosensing and novel metal micro / nano liquid crystal photovoltaic devices.
