Abstract
We have performed the first-principles calculations about the superconducting transition temperature TcTc of hole-doped delafossite CuAlO2, AgAlO2 and AuAlO2. Calculated TcTc are about 50 K (CuAlO2), 40 K (AgAlO2) and 3 K(AuAlO2) at maximum in the optimum hole-doping concentration. The low TcTc of AuAlO2 is attributed to the weak electron–phonon interaction caused by the low covalency and heavy atomic mass.
► Calculations about superconducting critical temperature of hole-doped delafossite. ► Calculated TcTc are about 50 K (CuAlO2), 40 K (AgAlO2) and 3 K (AuAlO2) at maximum. ► The difference in TcTc is attributed to not only atomic mass but also covalency.
