SUMMARY:Mass Fabrication of Micro/Nano Dual-scale Structures  and its Appl
 ications in Energy Harvesting - Prof. Haixia (Alice) Zhang\, Institute of

DESCRIPTION:This talk will introduce a top-down method to make mass produc
 tion of micro/nano dual-scale structures. Well-designed microstructures ar
 e fabricated by normal micro fabrication process\, while nanostructures ar
 e formed by following improved etching and growing process to realize micr
 o-nano dual structures. By combining the uniformed microstructures and nan
 ostructures on the same surface\, these MNDS structures have the unique pr
 operties\, such as anti-reflectivity\, super-hydrophobicity and super-high
 -density. The relationship of MNDS and its properties will be studied and 
 analyzed by a novel method\, 3D SEM reconstruction software\, which is dev
 eloped by the author’s group\, which can read cross-scale SEM photo into
  digital data and form the solid model for simulation automatically. Final
 ly\, some examples of using these MNDS in energy harvesting\, especially i
 n  triboelectric nanogenerator (TENG) will be demonstrated as a renewable\
 , clean and usable power source for smart system.
