Abstract
- Single crystals of In-doped PbBi2Te4 are synthesized via a conventional solid-state method. Chemical analysis and hall measurements indicate that In replaces Pb, introducing n-type carriers, creating Pb1-xInxBi2Te4. A superconducting transition is observed with a maximum transition temperature around 2.06 K for Pb1-xInxBi2Te4. Field dependent transport measurements reveal type-II superconductivity and yield a maximum upper critical field around 1.55 T. Thermodynamic data indicates bulk superconductivity in the BCS weak coupling limit. Our findings establish an ambient-pressure superconducting system in the AM2X4 family, and doped PbBi2Te4 as a promising platform for the study of topological superconductivity.<br />Comment: PRB accepted 11 pages main text + 4 pages SI
