Metal Oxide for Beyond CMOS

Oxides are a very large class of materials that demonstrate every electronic property known to science; including piezoelectricity, ferroelectricity, magnetism, superconductivity, and semi-conductivity. Not surprisingly, the 2015 semiconductor roadmap envisages that from 2022 onwards conventional CMOS will reach its limit and alternative Si/oxide technologies will drive further progress. The primary challenges here is identifying the “right” oxide for an application. By collaborating with computational physicists and materials scientists, we synthesize novel metal-oxides tailor-made for an application, and characterize their electro-optical properties.
