Abstract
In the present paper we have explained the temperature dependence of the thermal conductivity of KCl and NaCl by considering the separate contributions of longitudinal and transverse phonons. It is found that the transverse phonons make a major contribution towards thermal transport in these alkali halides.Keywords
