Misfit layered compounds have a crystal structure in which insulating layers and conducting layers are alternately stacked via van der Waals forces. The superconducting transition temperature (T_c) of (BiSe)_1.10(NbSe₂) is approximately 2.7 K, and it exhibits anisotropy in the upper critical field along the in-plane crystal axes. However, T_c is lower than that of NbSe₂ alone (T_c = 7 K), suggesting the potential for improvement in the transition temperature. In this study, we attempted to control T_c by introducing hole carrier doping into the NbSe₂ layers through elemental substitution. In this presentation, we will discuss changes in superconducting properties caused by Ag substitution.
