Stimulated Emission Depletion Spectroscopy of Color Centers in Hexagonal Boron Nitride
{{output}}
We demonstrate the use of Stimulated Emission Depletion (STED) spectroscopy to map the electron-optical-phonon sideband of the ground state of the radiative transition of color centers in hexagonal boron nitride emitting at 2.0-2.2 eV, with in-plane linear pol... ...
