Fig. 5: Strain effects on radiative recombination lifetime and ZPL energy.

a, b Uniaxial and c biaxial strain effects on radiative recombination lifetime τR. The inset in a shows the directions x and y. d, e Uniaxial and f biaxial strain effects on δE, modulation of the gap between corresponding eigenvalues (a1 to ex,y) in the ground state. The δE approximates the change of the ZPL energy, assuming the vertical shift of adiabatic potential energy curves occurs in the configuration coordinate diagram.
