“While the exact direction is still evolving, our immediate focus is on applying the THz-GSE-EPR technique to study paramagnetic point defects in ultrawide band gap semiconductors,” says Viktor Rindert, who’s the author of the study together with Vanya Darakchieva, Tapati Sarkar, and Mathias Schubert.
“This research is particularly relevant for power electronics applications, where such materials are critical in enhancing performance and efficiency,” says Viktor Rindert.
Materials interact with electromagnetic fields in different ways, reflecting their structures and underlying properties. The Lyddane-Sachs-Teller relation is a physics construct that describes the relationship between a material’s static and dynamic dielectric constant (i.e., values indicating a system’s behavior in the presence or absence of an external electric field, respectively) and the vibrational modes of the material's crystal lattice (i.e., resonance frequencies).
