Electronics for Sustainable Societies - Poster Prize Winners
Dr Ruomeng Huang - First Place Winner
Ruomeng studied Physics in China, receiving a BSc in 2008 and a MEd in 2009. He came to Southampton in 2009 where he obtained a MSc in Nanoelectronics and Nanotechnology in 2010 and a PhD investigating the confined nanoscale chalcogenide phase change material and memory in 2015. Following his PhD, Ruomeng was awarded an EPSRC Doctoral Prize fellowship in 2015 to start his independent research in functional chalcogenides and metal oxides with particular focus on application of novel non-volatile memory technologies (phase change memory and resistive switching memory) and thermoelectric (TE) materials and energy harvester. In 2018, he was appointed a lectureship in the Sustainable Electronic Technologies Group in the School of Electronics and Computer Science in the University of Southampton.
He was a Co-Investigator in a STFC grant (Selective Chemical Vapour Deposition for Production of Thermoelectric Micro-Generators for Energy Harvesting, £363k) for the development of thin film thermoelectric generators. He was also an investigator in a EPSRC program grant (ADEPT – Advanced Devices by ElectroPlaTing, £6.33m) which explores the state of the art of electrodeposition and device design at nanoscale in the areas of non-volatile memory (phase change and resistive memory), thermoelectrics, and infrared detection.
Ruomeng has published over 50 journal papers (Google Scholar) and delivered over 40 oral/poster presentations at national and international conferences. He is a regular reviewer of several journals from ACS, RSC and IEEE. He is currently guest editing a RSC Materials Advances theme collection of bioinspired artificial synapses and neurons based on memristors. He currently leads a team of 7 PhD students.
Two-terminal memristor is one of the most promising neuromorphic artificial electronic devices for their structural resemblance to biological synapses and ability to emulate many synaptic functions. In this poster, Dr Ruomeng Huang and co-workers from the University of Southampton report the development of back-end-of-line SiC and highly ordered nanoporous SiO2 based diffusive memristors that are capably of emulate several vital synaptic functions of human brain such as PPF, SRDP and SDDP. Both memristor demonstrate short-term plasticity (STP) behaviour which is essential for temporal information processing. A physical RC system based on the memristor has been experimentally implemented to perform a pattern recognition task with high accuracy. This work presents an important advance diffusive memristor and its application in both memory and neuromorphic computing.
