  AlN is a promising material for hosting quantum emitters and for use as optical waveguides. This work investigates the emission and structural properties of sputtered aluminium nitride thin films, with the aim of integrating these films into a quantum sensor.

  AlN is a promising host for quantum emitters, with an ultra-wide band gap, piezoelectric properties and widely used in industry. Recent reports indicate the presence of single-photon emitters (SPEs) in AlN [1,2], but the responsible defects are unidentified. This work aims to contribute towards such an identification by modelling intrinsic defects in AlN and their magneto-optical properties using density functional theory (DFT).
