Subject and UNIT: Physics for Electronics Engineering: Unit V: Nano Devices
Conventional electronic devices rely on the transport of electrical charge carriers - electrons. The 'spin' of the electron can be used rather than its charge to create a remarkable new generation of 'spintronic' devices. These are smaller, more versatile and more robust than those currently making up silicon chips and circuit elements
