报告摘要:
Materialsmade of nano/micro-structures have unique physical properties, such as fastcarrier transport, high surface-to-volume ratio, mechanical flexibility,sub-wavelength optical waveguiding, etc. These intriguing properties can beharnessed for a variety of applications in electronics and photonics. In thepast, we have fabricated an assortment of arrayed nanostructures consist ofnanowires, nanopillars, nanocones, etc., using a variety of materials frominorganic semiconductorsto organometal perovskite materials. Thesenanomaterials can be fabricated with chemical vapor deposition method and/orprintable method with scalability. The optical properties of thesenanostructures have been systematically investigated and the mechanism of lighttrapping was revealed. Meanwhile, the materials have been fabricated intovarious electronic devices, including sensors, light emitting diode and solarcells. The study has shown that three-dimensionally (3-D) arrayednanostructures can help to improve device performance as well as theflexibility. However, proper structural optimization is not trivial.Particularly, using printable method and template guided growth method,semiconductor nanowires have been fabricated into planar arrays and 3-D arraysfor photodetectors. Overall, the nanostructure integration methodology that wedeveloped may enable many applications on electronics and optoelectronics inthe future.
