Hexagonal boron nitride (hBN) has recently attracted significant research interest due to its unique properties. These include the chemical stability, its wide bandgap and the ability to host color centers inside the bandgap. These color centers exhibit bright and stable single photon emission at room temperature, which makes them interesting candidates for applications such as quantum communication and quantum sensing. To enable the direct pumping of color centers we examine the possibility to deposit hBN directly on LED and laser diode facets. As an intermediate step in this development, we report the results from spectroscopic measurements of hBN layers grown by pulsed laser deposition on silicon substrates as well as first tests on LEDs.
