Metal mesh filters based on Ti, ITO and Cu thin films for terahertz waves
In this study, we have investigated the spectral performance of resonant terahertz (THz) bandpass filters which were produced from thin films with a metal-mesh shape. The aforementioned filters were fabricated from titanium, ...
Investigation of electron beam lithography effects on metal-insulator transition behavior of vanadium dioxide
(IOP Publishing, 2017-10)
Vanadium dioxide (VO2) shows metal-insulator phase transition at nearly 68 °C. This metal-insulator transition (MIT) in VO2 leads to a significant change in near-infrared transmittance and an abrupt change in the resistivity ...
An indium tin oxide metasurface filter for terahertz applications: Design, fabrication, and characterization
(World Scientific Publishing, 2017-03)
In this paper, using a cross-shaped complementary Indium Tin Oxide (ITO)-based metasurface design, the transmission of THz radiation is shown to be filtered within the 3 dB level from maximum in the frequency range of ...
Fourcross shaped metamaterial filters fabricated from high temperature superconducting YBCO and Au thin films for terahertz waves
(IOP Publishing, 2017-06)
In this study, we present a new, unique fourcross shaped metamaterial terahertz (THz) filter fabricated from both gold thin films and YBa2Cu3O7-δ high Tc superconducting thin films. A commercial electromagnetic simulation ...
Area dependence and influence of crystal inhomogeneity on superconducting properties of Bi2212 mesa structures
The rapid increase in applications of terahertz waves requires new techniques to obtain continuous wave terahertz sources. Mesa structures fabricated from high-Tc superconductor Bi2Sr2CaCu2O8+δ (Bi2212) single crystal have ...
Comparative study of annealing and gold dopant effect on DC sputtered vanadium oxide films for bolometer applications
Vanadium oxide (VOx) thin film has been widely used for IR detectors and it is one of the promising materials for THz detectors due to its high temperature coefficient of resistance (TCR) values. VOx films with proper TCR ...
