Fig. 4: Temperature dependence of quantum interference.
From: Quantum interference between dark-excitons and zone-edged acoustic phonons in few-layer WS2
a, b Temperature-dependent Raman spectra of TA(M) and ZA(M) and LA(M) phonon modes in 2L and 3L WS2 with 612 nm excitation. The intensities are normalized to the LA(M) mode. The star symbol indicates the second-order phonon mode: E\({}^{{\prime} }\)(M) - LA(M). The data are offset for clarity.
