摘要: Abstract Amorphous buffer layers of TaIr, sandwiched between YBaCuO thin films and Si(100) substrates, prevent interface reactions during annealing in oxygen ambient up to 800 °C. Above 650 °C, amorphous TaIrO, which is formed annealing, crystallizes into Ta 2 O 5 IrO , pinholes the film layer are observed. Reaction with silicon does not occur after 900
