van Hattem, A. (author), Griveau, Jean Christophe (author), Colineau, Eric (author), Lefering, A.J.E. (author), Konings, R. (author), Smith, A.L. (author) The heat capacities of CsPbI<sub>3</sub>, Cs<sub>4</sub>PbI<sub>6</sub>, and Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub> were studied using low-temperature thermal relaxation calorimetry in the temperature range of 1.9-300 K. The three compounds are insulators, with no electronic contribution to the heat capacity. None of them show detectable...
