Chennupati Jagadish (The Australian National University, Canberra, Australia): Semiconductor Nanostructures for Optoelectronics Applications




15/11/2024 at 16.00, Room Conversi, Dip. Fisica building Marconi

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 present the results on growth of nanowires, nanomembranes and microrings and their optical properties. Then I will discuss theoretical design and experimental results on optoelectronic devices. In particular I will discuss nanowire and micro-ring lasers and integration of nanowires and microrings. I will also present the results on polarization sensitive, broad bandwidth THz detectors operating at room temperature. Nanowire based energy devices such as solar cells and photoelectrochemical (PEC) water splitting will be discussed. I will discuss about Neuro-electrodes to study brain signaling to understand dementia. Future prospects of the semiconductor nanostructures will be discussed.

Professor Jagadish is a Distinguished Professor and Head of Semiconductor Optoelectronics and Nanotechnology Group in the Research School of Physics, Australian National University. He has received Australia’s highest civilian honor, AC, Companion of the Order of Australia, for his contributions to physics and engineering, in particular nanotechnology. He has received 2023 Pravasi Bharatiya Samman Award, highest award given to overseas Indians by the Government of India, from the President of India. He is currently serving as the President of the Australian Academy of Science and in the past served as President of IEEE Photonics Society, IEEE Nanotechnology Council and Australian Materials Research Society. He has received honorary doctorates from University of Surrey and Nottingham Trent University in July 2024.
