The negatively charged boron vacancy (VB⁻) in hexagonal boron nitride is a spin defect that can be read out optically at room temperature. Because it lives inside a layered crystal only nanometers thick, it can sit right against whatever it is sensing. The project creates these defects on purpose by irradiating exfoliated flakes, then checks the result with photoluminescence mapping and ODMR. My part includes the PL analysis pipeline, bench tools for PL and AFM data, and Monte Carlo simulation for choosing beam conditions.
