Özet
As is known, cuprate superconductors, which have intrinsic Josephson junctions, are used as terahertz sources. In this context, a great number of studies on the intensification of the plasma frequency in terahertz region are devoted to the fabrication of mesa structures in superconductors. It has been previously investigated by some researchers that the resonant state of cuprate superconductors enhances the power of the plasma frequency in terahertz range. As is known, the mercury-based superconductors exhibit three-dimensional Bose-Einstein condensations; hence the resonant state occurs in the sample. From this point of view, mesa structures, which are intrinsically formed in mercury cuprates, have been investigated to enhance the plasma frequency in this work. Also, I have found a physical relation between the lateral size and the Josephson penetration depth of the superconducting sample. Moreover, it has been found that at upper and the lateral size values with microdimension, the superconductors investigated behaves as a bulk in the context of the critical parameters. Furthermore, the method recommended in this study would make crucial contributions to technological applications on mesa structures in order to determine the convenient mesa size that prevents vesting time and energy for the fabrication.
