Abstract: The advent of graphene and other 2D materials offers great potential for optoelectronics applications. Various device structures and novel mechanisms have been proposed to realize photodetectors with unique detecting properties. In this talk, we report the results for two metal-semiconductor-metal (MSM) photodetectors with asymmetric contacts based on graphene and a member of the transition metal dichalcogenides family, WSe2, which enable the self-driven characteristics that is absent in conventional MSM photodetectors. In the first configuration (Au-WSe2-Graphene), both the Au-WSe2 and WSe2-Graphene contacts are formed by PDMS-mediated dry transfer techniques, with two asymmetrical van der Waals contacts formed to yield the proposed structure. When the device is under illumination at a wavelength of 650 nm, a large photocurrent is measured. Further, an open-circuit voltage Voc and a short-circuit current Isc are clearly observed, indicating the self-driven properties of the MSM photodetectors. The Voc and Isc can also be tuned by a back-gate voltage, which results from the tunable Schottky barrier height along with the gate tunable carrier concentration in WSe2. In the second device configuration (Au-WSe2-Au), the same type of Schottky barrier is formed while the contact lengths of the two Au-WSe2 junctions are designed and fashioned to be different to result in a net Isc. This self-driven photodetector with asymmetric contacts has great potential for low-power or even powerless operation. Combining the wide spectra covered by various 2D materials with different bandgaps, it is expected that the self-driven 2D-materials-based photodetectors can supplement the current mainstream silicon and compound semiconductor-based photodetectors which can only detect a narrow range of the optical spectrum.

IEEE MTT-S DISTINGUISHED MICROWAVE LECTURE: MICROWAVE PHOTONIC RADARS: WHAT CAN PHOTONICS BRING TO RADARS? (8 April 2024)
As the only method for all-weather and long-distance target detection and recognition, radar has been intensively studied since it was proposed, and is considered as an essential sensor for future intelligent society. In the past few decades, great efforts have been devoted to improving radar’s functionality, precision, and response time, of which the key is to generate, control, and process a wideband signal at a high speed. Thanks to the high frequency, large bandwidth, low loss transmission, and electromagnetic immunity provided by modern photonics, implementation of the radars in the optical domain can provide better performance in terms of resolution, coverage, and speed which may not be achievable using traditional, even state-of-the-art electronics. In this talk, I'll give an overview of the photonic technologies that are currently known to be attractive for radars. System architectures and their performance that may interest the radar society are emphasized. Emerging technologies in this area and possible future research directions are discussed.

IEEE UTS Student Branch Honors International Women's Day (8th March 2024)
The IEEE Student Branch at the University of Technology Sydney celebrated International Women's Day on March 8, 2024, with enthusiasm and dedication. Organized by the Chair, Mohammad (Behdad) Jamshidi, and the women's executive board, including Shaghayegh Chamani, WiE Affinity Chairwoman, Maryam Fallahpoor, WiE Affinity Vice-Chairwoman, and Mina Feizi, Event Leader, the event showcased the commitment of the IEEE UTS SB to gender equality and empowerment in STEM fields. It emphasized the significance of supporting and celebrating women's achievements in engineering and information technology, aligning with global efforts to promote diversity and inclusion within the tech industry. This celebration not only honored women's contributions but also inspired the community to continue advocating for gender balance in STEM.
Rethinking the Human-Robot Relationship (11 April 2024)
As robotics and AI technologies rapidly advance, the relationship between humans and AI-powered robots is undergoing profound transformations. In this talk, we will review the evolution of human-robot relationships, discuss technological advances, including research conducted over the last 20 years at UTS. Prof.Liu will also delve into the dynamics of collaboration between humans and robots, examining issues such as trust, role change, human-centered design, computational modelling, and interface. Additionally, we will cover many questions about ethical considerations, cultural perspectives, and regulations to govern the development and deployment of intelligent robotics technology. Our aim is to contribute to a more ethical and harmonious human-robot relationship by fostering dialogue and collaboration among stakeholders.
