The thermal conductivities of the \GAs\ are measured to be 0.12–0.36 W/(m K). This is the first systematical study of the thermal properties of \GAs\ and the results elucidate the factors limiting their thermal conductivities. The developed thermal measurement technique can be applied to other porous material systems.
