Abstract
Hexagonal boron nitride (hBN) has been gaining attention as a compelling material platform hosting quantum emitters at room temperature. A particularly important family of emitters in hBN are those with a zero phonon line at 436 nm (termed B-centers) since these can be engineered on demand using electron beam irradiation. In this work, we demonstrate a pathway to integrate these emitters with plasmonic lattices. The blue wavelength necessitates the use of aluminum metal, instead of gold or silver. Consequently, we utilize trench cavity geometry and transfer hBN layers on top of the lattice. We then create deterministically the emitters and measure a 6-fold enhancement in the emission intensity. We conclude by discussing the potential possibilities of plasmonic lattice arrays for scalable enhancement of quantum emitters in layered materials.
