摘要：
Epitaxial YBCO thin films have been grown on MgO, SrTiO3 and NdGaO3 substrates by a new process (injection MOCVD). Droplets (few mu l) of a solution of Y, Ba and Cu beta-diketonates in monoglyme are injected into an evaporator through a fast micro electro-valve driven by a computer. Growth rates mon than ten times higher than those obtained by the conventional MOCVD process have been obtained in this first step of experiments (>3 mu m h(-1)). The best films obtained so far have T-c>90 K and J(c)>3x10(6) A cm(-2).
