Table 1 Range for the lifetimes of acoustic and optical phonons in CsPbBr3, calculated for different temperatures
From: Dynamic shortening of disorder potentials in anharmonic halide perovskites
Temperature (K) | Acoustic modes (ps) | Optical modes (ps) |
|---|---|---|
325 | 0.5–9.5 | 0.3–4.6 |
425 | 0.4–6.7 | 0.3–4.4 |
525 | 0.5–5.4 | 0.3–2.8 |
