Project description

This PhD studentship aims at developing radiation-hardened memristive artificial synapses for enabling artificial intelligence hardware accelerators in space. The conventional logic and memory technologies that are available in the market today are prone to electronic failures toward photon and particle radiations. Thanks to the memristor's architectonic, the memristive system is intrinsically rad-hard element and brings promises for smaller, faster, and lighter electronics that are beneficial in reducing the space payload and prolonging the electronic lifespan in harsh and inaccessible environments. The students will investigate the capability of the memristors in emulating the biological synapses and the devices potential in exploiting the electrical feedback from the particle and photon radiations. The students can also study the reliability of the memristor arrays as a neuromorphic computation element and conduct real-time experiments/measurements where these memristors will be launched to space (low earth orbit). The co-integration of computing and sensing functionalities of the fabricated devices will also be explored.

1. Nanodevice engineering

Focuses on the device fabrication of rad-hard artificial synapse memristor (1R) and selector (1S) stacks, their integration (1S1R) in cross-bar array configurations, and exploits their radiation tolerance and sensitivity.

2. Materials and/or electrical (device) modelling

Focuses on numerical analysis or simulation of the physical, chemical, and/or electrical behavior of the fabricated nanodevices to elucidate the observed phenomenon or anomaly due to radiation.

3. Neural network modelling

Focuses on the simulation and implementation of the fabricated devices for neuromorphic computing applications (such as image processing, pattern recognition, data clustering, etc.) and investigate the training accuracy irregularity due to the radiation damage and explore the mitigation algorithm and/or exploit such irregularity for making adaptive electronics.

The PhD student will have the opportunity to join a multi-disciplinary team and be trained and work in the world-class facilities of the Zepler Institute for Photonics and Nanoelectronics. The Centre for Electronics Frontiers will provide research experience in one of its programs, training, laboratory facilities, and access to its seminar and lectures. Students would also be encouraged to visit our collaborators' and industry partners' facilities (space, particle accelerator, and radiation research facilities) in the UK or abroad, as well as to attend major conferences during their period of study.
