Abstract
In this observational study, we embed few-layer hexagonal boron nitride
(hBN) inside a planar Fabry–Perot cavity fabricated using a pulsed DC
magnetron sputtering system and show that the hBN retains its inherent
visible range, defect-based luminescent properties following
relatively energetic deposition processing. The observed
surface-normal emission enhancement factor of ∼40 is in good agreement with theoretical
predictions. We also found that embedded hBN subjected to a rapid
thermal annealing treatment exhibits a cracking effect where the edges
of the material glow distinctly brighter than adjacent regions. Our
results might inform future efforts involving monolithic integration
of hBN active layers.
