摘要：

The surface resistance R(s) and the absolute value of the magnetic penetration depth lambda of ultrathin YBa2Cu3O7-delta filMS on silicon are determined by THz-pulse transmission experiments. We find a minimal value of R(s) for a film thickness of about 30 nn. The increase of R(s) with film thickness above 30 nm reveals an increase of the density of weak links possibly associated with the formation of microfractures even below the critical film thickness of 50-70 nm.
