Thesis Title - "Synthesis and Characterisation of Transition Metal Oxides (TMOs) Thin Films for Memristive and Neuromorphic Application"

Advisor - Prof. Ankur Goswami

My research focuses in optimizing the growth and the characterization of thin film transition metal oxides and polymer based memristor suitable for neuromorphic computing. I have synthesized the growth of vanadium dioxide and strontium titanate thin film using pulsed laser deposition (PLD) on top of silicon and sapphire wafers. This was followed by fabrication of memristor through lithography. The core aim of my research was to obtain an improved state of the art parameters of the fabricated memristors in terms of R_OFF/R_ON ratio, switching power, endurance and data retention period. The devices were also tested for synaptic plausibility using spiking time dependent plasticity (STDP) study. A biocompatible memristor was also fabricated by spin coating protonated polyaniline-polystyrene blend thin film on top of conducting glass substrate and was characterized along similar lines as the devices mentioned above.
