Semiconductor Nanowires for Optoelectronics Applications

Semiconductors have played an important role in the development of
information and communications technology, solar cells, solid state lighting. Nanowires
are considered as building blocks for the next generation electronics and optoelectronics.
In this talk, I will introduce the importance of nanowires and their potential applications
and discuss about how these nanowires can be synthesized and how the shape, size
and composition of the nanowires influence their structural and optical properties. I
will present results on axial and radial heterostructures and how one can engineer the
optical properties to obtain high performance lasers, THz detectors and solar cells. Use
of nanowires for artificial photosynthesis and engineering of neuronal networks will be
discussed. Future prospects of the semiconductor nanowires will be discussed.
"” Professor Jagadish is a Distinguished Professor and Head of Semiconductor
Optoelectronics and Nanotechnology Group in
the Research School of Physics and Engineering,
Australian National University. He is currently serving
as President-Elect of IEEE Photonics Society and
President of Australian Materials Research Society.
His research interests have been in MOVPE growth
of semiconductor heterostructures and nanowires,
their characterization and optoelectronics device
applications. He was an early pioneer in the study
of impurity induced disordering in semiconductor
heterostructures. His research contributions have
been recognized by many international awards
including the Quantum Device Award from
ISCS in 2010, Electronics and Photonics Division
Award of the Electrochemical Society in 2012,
2013 Walter Boas Medal, 2015 IEEE Pioneer Award
in Nanotechnology, 2015 IEEE Photonics Society
Engineering Achievement Award, 2016 Distinguished
Fellow of Chinese Academy of Sciences, 2016 OSA
Nick Holonyak Jr Award, 2017 Welker Award and 2017
IUMRS Somiya Award. He has received Australia's
highest civilian honor, Companion of the Order of
Australia, as part of the 2016 Australia day honors
from the Office of the Governor General for his
contributions to physics and engineering, particularly
nanotechnology.
