Composition-dependent lattice strains and lattice thermal conductivity () for NaEu0.03Mn0.03Pb0.94-Te with a 48-hour annealing at 900 K (a); annealing time-dependent lattice strain (at 900 K), and for Na0.03Eu0.03Mn0.03Pb0.91Te (b); lattice strain-dependent with a comparison to model prediction for Na0.03Eu0.03Mn0.03Pb0.92Te (c); and annealing time-dependent Hall mobility and carrier concentration (d) for Na0.03Eu0.03Mn0.03Pb0.91Te.
