Abstract: We performed ultra-low temperature thermal conductivity measurements on the single crystal of a new gold-based quasi-two-dimensional superconductor AuTe2Se4/3,which has a superconducting transition temperature Tc =2.70 K.A negligible residual linear term κ0/T in zero magnetic field is observed,which suggests fully gapped superconducting state.Furthermore,the field dependence of ko/T is similar to that of the multi-band s-wave superconductor BaFe1.9Ni0.1As2 at low field.These results reveal multiple nodeless superconducting gaps in this interesting quasi-two-dimensional superconductor with Berezinsky-Kosterlitz-Thouless topological transition.
