Course content

The course provides a fundamental understanding of the physical principles responsible for the properties of important functional materials, with emphasis on the design of material properties for energy-efficient device technologies, emerging and potential engineering applications, and sustainability.

The course covers:

Li-ion batteries and Solid-state batteries. Anode materials (conversion, intercalation, alloys), cathode materials (conversion, intercalation), electrochemical potential of electrode materials, solid-state electrolytes, ionic and electronic transport in solids, interfacial properties in solid-state batteries. Key challenges in solid-state battery development and their mitigation strategies.

Materials for future nanotechnology: Introduction to symmetry analysis of solids and the Landau theory of phase transitions; ferromagnetic and ferroelectric memories; flexoelectricity; skyrmions and vortex structures; improper ferroics, multiferroic and magnetoelectric devices; epitaxial engineering of heterointerface properties and domain wall properties; memristive memories, artificial synapses and neuromorphic circuitry.

Learning outcome

The course will enable the students to:
