Reduction of Lattice Thermal Conductivity in PbTe Induced by Artificially Generated Pores

Figure 1

X-ray diffraction patterns of (a) PbTe PbTe + NaCl (b) before and (c) after sonication, and (d) PbTe + PVA (d) before and (e) after sonication. Asterisk () represents NaCl phase and green dotted lines are guidelines for peak positions.
