| description | In this work, a new crystal growth technique called the liquid transport method was introduced to synthesize single crystals of a topological superconductor candidate, In<i><sub>x</sub></i>Sn<sub>1−<i>x</i></sub>Te (IST). Crystals with the size of several millimeters were successfully synthesized, and were characterized by X-ray diffraction, scanning electron microscopy with energy-dispersive spectroscopy as well as electronic transport measurements. Lattice parameters decreased monotonously with the increase of indium content while hole density varied in reverse. Superconductivity with the critical temperature (<i>T</i><sub>c</sub>) around 1.6 K were observed, and the hole densities were estimated to be in the order of 10<sup>20</sup> cm<sup>−3</sup>. The upper critical fields (<i>B</i><sub>c2</sub>) were estimated to be 0.68 T and 0.71 T for In<sub>0.04</sub>Sn<sub>0.96</sub>Te and In<sub>0.06</sub>Sn<sub>0.94</sub>Te, respectively. The results indicated that the quality of our crystals is comparable to that grown by the chemical vapor transport method, but with a relatively larger size. Our work provides a new method to grow large single crystals of IST and could help to solve the remaining open questions in a system that needs large crystals, such as a superconducting pairing mechanism, unconventional superconductivity, and so on. |
