Abstract

Man-made computers are based on circuits of functional units that follow given design rules. On the other hand, natural computers exploit the emergent properties and massive parallelism of interconnected networks of locally active components to perform highly complex computational tasks like navigation, recognition, and decision-making. In this talk, I will summarize my efforts to understand the dynamics of disordered networks of nanoscale components to realize computational architectures. In recent report, we have shown that interconnected metal nanoparticles acting as strongly nonlinear single-electron transistors can be configured in situ into any Boolean logic gate. For this purpose, the electrical properties were artificially evolved, using genetic algorithm, to perform computational tasks reconfigurably. I will also discuss our current efforts to emulate biological neuronal structures with percolating nanoparticle network. These are similar to the brain-architecture and naturally incorporate the necessary complexity and criticality. These self-assembled switching devices are promising for brain-inspired neuromorphic architecture suitable for fault-tolerant computation and real-time on-chip pattern recognition.

Biography

Bio: Dr. Saurabh Bose is an experimental condensed matter physicist interested in low dimensional electronic systems. His research vision is to utilize charge and spin degrees of freedom in nano-devices for technological advancement for the benefit of our society. Keeping application as the ultimate goal, he enjoys investigating physical phenomenon in quest to understand the fundamental laws governing the reality. His broad research interests are spin-and electronic-transport in organic-inorganic hybrid structures, Neuromorphic systems, and thin film heterostructures.

After completing his Doctorate from I.I.T. Kanpur, India he worked in the University of Twente, Netherlands as postdoctoral researcher. In 2015, he moved to University of Canterbury, where he is currently working on designing and developing brain-inspired Neuromorphic devices from metal nano-clusters.
