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.


Dr. David J. Meyer graduated from The Pennsylvania State University in 2008 with a Ph.D. in Materials Science and Engineering and then joined the Naval Research Laboratory (NRL). In 2020, he was promoted to head of the Electromagnetics Technology Branch where he currently manages approximately 30 materials scientists, electrical engineers, physicists, mathematicians, post-docs and technicians who perform a host of research projects related to the development of solid-state and vacuum electronics technology for microwave and millimeter-wave applications. Dr. Meyer is a senior member of IEEE and was awarded the Dr. Delores M. Etter Top Navy Scientists and Engineers Award in 2017 and the Sigma Xi Young Investigator Award in 2018. He has co-authored over 75 journal articles and 70 invited talks.
