Abstract
Novel articles are provided of thin super-conductive thallium-based copper oxide layers on inorganic, usually crystalline substrates. Novel methods are provided for ease of producing such articles, particularly involving sol-gel techniques and laser ablation. The articles have a highly oriented superconductive thallium-based copper oxide film, particularly epitaxial, with high superconductive transition temperatures and desirable electrical properties. The subject articles find use in a wide variety of electronic applications, particularly in microwave and millimeter wave devices.
