Fig. 1: Ideal crystal structure and thermal conductivity of InTe single crystal.

From: Direct observation of one-dimensional disordered diffusion channel in a chain-like thermoelectric with ultralow thermal conductivity

Fig. 1

a, b Illustration of the reported ideal crystal structure of InTe along the c axis (a) and the [110] direction (b). c XRD patterns of the cleavage surfaces of InTe single crystal for the determination of the crystallographic directions. The intersection line of the two perpendicular cleavage planes (hh0) determines the c axis. The inset photo shows the cleaved crystal with two perpendicular cleavage surfaces of A and B. d Measured temperature-dependent thermal conductivity of InTe single crystal along the [001] direction. The reported thermal conductivity data along [001] and [110] directions of InTe single crystal from refs. 22,23 are plotted for comparison. The PPMS and LFA denote the Physical Property Measurement System and Laser Flash Apparatus for the low- and high-temperature thermal conductivity data measurements, respectively.
