Open AccessGiant shift upon strain on the fluorescence spectrum of VNNB color centers in h-BN
We study the effect of strain on the physical properties of the nitrogen antisite-vacancy pair in hexagonal boron nitride (h-BN), a color center that may be employed as a quantum bit in a two-dimensional material...
