High quality, epitaxial TlBaCaCuO films on MgO and sapphire substrates will be prepared. However, some problems exist for such epitaxial growth and it is proposed to overcome these difficulties by buffering the substrate using an inert epitaxial layer, which has a close lattice match to the TBCCO structure. Growth of epitaxial Tl-based films via an established post deposition annealing process on top of thin, high quality CeO2 buffer layers will be undertaken. If successful, this process could replace much of the material currently grown on LaAlO3 for microwave components at high frequencies where frequency settability is a key issue.

将准备高质量的外延tlbacacuo胶片和蓝宝石底物上的薄膜。 但是，这种外延生长存在一些问题，并提出通过使用惰性外延层缓冲底物来克服这些困难，该层与TBCCO结构密切相匹配。 将在薄质的高质量CEO2缓冲层上通过已建立的后沉积退火过程增长外延的基于TL的膜。 如果成功，此过程可以替换在Laalo3上当前生长的许多材料，用于在频率可达性是关键问题的高频下的微波组件。
