(a) Phonon spectra of the TO mode at the K point at different temperatures for unstrained monolayer h-BN. (b) Phonon spectra of the TO mode at the K point at different temperatures for εx = εy = 0.14. (c) Temperature-dependent linewidth of the TO mode at the K point for εx = εy = 0, 0.10, 0.12 and 0.14. (d) Temperature-dependent frequency shift of the TO mode at the K point for εx = εy = 0, 0.10, 0.12 and 0.14.
