Sub-kelvin Andreev reflection spectroscopy of superconducting gaps in FeSe
Sub-kelvin Andreev reflection spectroscopy of superconducting gaps in FeSe
Point contact Andreev reflection studies have been conducted on FeSe single crystals by lowering the temperatures down to 0.5 K. The point contact Andreev reflection spectra were analyzed in the framework of the two-band model. As a result, the presence of two anisotropic superconducting gaps in FeSe were certainly established …
