A theoretical model suggests that while point defects in alloys efficiently scatter short-wavelength phonons, the ErAs nanoparticles provide an additional scattering mechanism for the mid-to-long-wavelength phonons.©2006 The American Physical Society</style></abstract><notes><style face="normal" font="default" size="100%">2007 Goldsmid Award Winner</style></notes></record></records></xml>
