The paper presents the results of studies of monoatomic layers of graphene obtained using the CVD method on a copper foil, followed by transfer to a sapphire substrate. The basic electrophysical parameters of graphene samples were measured. Their irradiation with neutrons in the nuclear research IBR-2 reactor was carried out up to the fluences of 4.5·1019 n·m−2. A comparison of the Raman spectra before...
Characteristics of superconducting FeSe0.5Te0.5 hot electron bolometer are reported. The superconducting FeSe0.5Te0.5 film is grown by pulsed laser deposition on MgO substrate, and its transition temperature and complex conductivity indicate that the film quality is good enough for hot electron bolometer. We then fabricate hot electron bolometer based on the superconducting FeSe0.5Te0.5 film, and...
We have investigated superconducting properties of niobium titanium nitride (NbTiN) films to be used for the lower and upper electrodes of a microstrip line with a SiO2 insulator on a quartz substrate at Terahertz frequencies. NbTiN films were prepared on a 1-mm thick quartz substrate directly (assumed to be the lower electrode of the microstrip line) and on an about 150-nm thick SiO2 layer sputtered...
Time-reversed electromagnetic wave has the property of spatial super-resolution focusing in far-field circumstances. This paper provides a novel method to design compact multi-antenna for wireless communication system using time reversal super-resolution property. A new type of planar microstructured antennas with the super-resolution of 1/15 wavelength is constructed and simulated with the aid of...
We studied a low temperature deposition of tungsten-alloy barrier and copper layers only by electroless plating, with an aim of realizing low resistance TSV with a high aspect ratio. We succeeded in successive deposition of W-Ni-P barrier layer and Cu on SiO2. Furthermore, we found that the addition of Cl ions to SPS- and PEG-plating bath significantly improved the conformal deposition property even...
