Programme Highlight
Materials made of
nano/micro-structures have unique physical properties, such as fast carrier
transport, high surface-to-volume ratio, mechanical flexibility, sub-wavelength
optical waveguiding, etc. These
intriguing properties can be harnessed for a variety of applications in
electronics and photonics. In the past, we have fabricated an assortment of
arrayed nanostructures consist of nanowires, nanopillars, nanocones, etc.,
using a variety of materials from inorganic semiconductors to organometal
perovskite materials. These nanomaterials can be fabricated with chemical vapor
deposition method and/or printable method with scalability. The optical
properties of these nanostructures have been systematically investigated and
the mechanism of photon management was revealed. Meanwhile, the materials have
been fabricated into various electronic devices, including sensors, light
emitting diode and solar cells. The study has shown that three-dimensionally
(3-D) arrayed nanostructures can help to improve device energy conversion
efficiency as well as the mechanical flexibility. However, proper structural
optimization is not trivial. Meanwhile, using printable method and template
guided growth method, semiconductor nanomaterials have been fabricated into 3-D
arrays for high density device applications. Overall, the nanostructure
integration methodology that we developed may enable many applications on
integrated electronics and optoelectronics in the future.
