TITLE: "Excitons and Quantum Sensing with Defects in Semiconductors”
ABSTRACT: Quantum sensing is a paradigm shift, relying on the intrinsic sensitivities of quantum state to their surrounding environment to detect extremely small changes in temperature, magnetic, and electric fields. Quantum sensing, among the diverse range of emerging quantum science applications such as computing and communication, is gaining increasing recognition as a viable technology, with commercially available products already making their mark in the market. The success of quantum sensing using nitrogen-vacancy (NV) defects in diamond under ambient conditions has sparked a growing interest in discovering other solid-state defects in wide bandgap semiconductors with comparable properties. In this talk, our recent results on the characterization of defects in 3C and 4H SiC, cubic boron nitride, 2D transition metal dichalcogenides (TMDs) for quantum sensing applications will be presented. Exciton dynamics in 2D TMDs will be discussed. Our recent achievements in miniaturization of NV diamond based quantum sensor devices will be also covered.
