Dr Alain Nogaret
Profile
Research Interests
My research has two themes: low dimensional electron systems confined by microscopically inhomogeneous magnetic fields, and micromachined transmission lines that propagate electrical impulses and mimic biological nerve fibres. I have shown theoretically that spin resonance can be excited by injecting an electrical current through a magnetic field gradient and is currently seeking to detect its fluorescence emission in order to develop nanoscale wireless transceivers. I also demonstrated the feasibility of propagating electrical impulses through non-linear semiconductor wires and am currently bulding neuron-like devices for applications in neural networks that compute temporal trains of discrete action potentials or ‘spikes’.
