The overarching goal of the proposed effort is to carry out basic research in science and engineering in order to unveil the physics of light interactions with Weyl semimetals; to assess both theoretically and experimentally their potential for advanced optoelectronics, electronics, and spintronics circuitry and components; envision new applications based on their unique properties; and interface their interactions with classical and quantum light. These aspects will be considered as a guideline in designing novel Weyl semimetal material systems that can overcome their current shortcomings.
In this effort we intend to explore a number of topics:
-
Design from first principles, growth, and characterization of multi-functional non-magnetic and magnetic, both Type-I and Type-II Weyl semimetals with enhanced optoelectronic properties, tailored to intended applications
-
Design, fabrication, and characterization of meta-structures capable of interfacing with Weyl semimetals in order to further boost the associated light-matter interactions. This is particularly important since there is still debate about the origin of some of the properties observed in various WSMs
-
Exploring a variety of opportunities provided by their symmetries for a new generation of photonic materials and structures like detectors, switches, integrated polarization devices, non-reciprocal elements, and modulators
-
Investigating the possibility for Weyl inspired photonic arrangements that can exhibit new and improved optical and optoelectronic properties and functionalities.
