Abstract: In this seminar, I will present an overview of the research activities of my group, the CU Aerospace Nanoscale Transport Modeling (CUANTAM) Laboratory. In CUANTAM Laboratory, we design and discover new materials to realize future technologies. Additionally, we discover novel pathways to transport energy and information in nano- to microscale materials that will transform existing technologies. We combine concepts from solid state physics, materials chemistry, nano- to microscale device physics and engineering, and contribute to four research fields:

  1. Artificial Intelligence for Materials Discovery focuses on the application of data-driven approaches for rapid design and discovery of novel materials and structures for a broad range of technologies. Our projects include Materials Design for Thermoelectric and Microelectronic Technologies and Hypersonic Vehicles.
  2. Designing Materials for Harsh Environments: High temperature, oxidation or radiation conditions strongly affect the properties of materials and their performance in applications. We investigate the change of materials properties and design materials that can sustain extreme environments. Our projects include Materials Design for Thermal Barrier Coating, Hypersonic Vehicles and Radiation-Hard Microelectronics.
  3. Thermal Management: Ultra-high-frequency lattice vibrations, known as phonons, are the heat energy carriers that determine the heat conduction properties of materials. We develop strategies to control, manipulate and guide phonons in materials. Efficient thermal management will improve thermal protection systems, and is key to realize faster, more reliable and energy efficient devices. Our projects include Materials Design for Thermoelectric Technology and Development of Thermal Model of Microelectronics.
  4. Tuning Interaction Between Energy/Information Carriers: Recent research uncovered fundamentally new quantum sensing, memory, and computing paradigm by manipulating interaction between information carriers such as polarizations of a photon or spin states of an atom or an electron. We investigate strategies to control and manipulate the interaction between quantized electron spin waves and lattice vibrations for solid-state quantum memory and transduction applications.
