Geometric Control of Visible Emitter Creation in Hexagonal Boron Nitride by Oblique Ion Irradiation
Sagar Chowdhury, Bhaveshkumar Kamaliya, Ramachandra Bangari +5
Ion irradiation creates optically active defects in wide-bandgap van der Waals materials, yet most approaches tune defect formation by varying the ion species, energy, or fluence w…
