An international team of researchers (China, USA – University of Tennessee, Israel) reported the experimental evidence for the unconventional superconductivity generated by the surface states in TaIrTe4 from both scanning tunneling microscopy/ spectroscopy (STM/STS) and electrical transport measurements. They demonstrated its superconductivity by both the superconducting gap from STS and the consistent resistance drop from electrical transport. The thickness-independence of ultralow critical current and angular dependence of upper critical field (Bc2) indicate that the superconductivity occurs only in the surface states. The research offers a novel platform for exploring topological superconductors and may contribute to the rapidly developing field of topological quantum computation…read more.
