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 ...
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 ...
Fabrication of Bi2212 single crystal bolometer for detection of terahertz waves
Terahertz (THz) radiation is in powerful region of electromagnetic spectrum because of prosperous application areas yet deficiency still exists about sources and detectors in despite of improvements of the research field ...
