Transition Metal-based Materials for Novel Hybrid Coupled-phenomena Device Platforms

Compound semiconductor devices based on Group II, III, V and VI elements have long been pursued because of their advantageous electrical properties such as high carrier mobility and saturated velocity, wide bandgap and high breakdown strength, and ability to support heterostructure band engineering. As new techniques are established that enable epitaxial integration of dissimilar materials, there is an emerging realization that new hybrid device functionality with advanced performance can be attained if multiple material aspects (such as mechanical, thermal, optical, and electrical) can be combined. Transition metals, in particular, enable numerous opportunities to incorporate high performance piezoelectrics, ferroelectrics, superconductors, phase change materials, spectral emissivity/absorptivity tunability, functional defect formation and others with conventional compound semiconductor materials. This talk will give a few examples of new coupled-phenomena devices that leverage phonon-electron, phonon-qubit, photon-polariton, and photon-electron interactions for applications in quantum acoustodynamic systems, advanced RF signal processing, and optical sources and detectors.
