Room temperature spin coherence in defect-engineered monoisotopic hBN

ORAL

Abstract

Negatively charged boron vacancies in hBN have attracted attention for their optically addressable room temperature spin coherence, making them an attractive choice for quantum information and sensing applications in a 2D material platform. We present room temperature infrared photoluminescence (PL) and optically detected magnetic resonance (ODMR) experiments on hBN as a function of isotopic composition and varying doses of neutron irradiation. We also employ PL and ODMR microscopy at low temperature to characterize the spatial distribution of defects in these materials with an eye towards improving material properties for quantum information and sensing applications.
