Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics
Advanced Science, EarlyView.Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...
