The integration of low-dimensional materials with optical waveguides presents promising opportunities for enhancing light manipulation in passive photonic circuits. In this study, we investigate the potential of aerosol-synthesized single-walled carbon nanotube (SWCNT) films for silicon nitride photonic circuits as a basis for developing integrated optics devices. Specifically, by measuring the optical response of SWCNT-covered waveguides, ...

The schematic design of electronic devices for harsh environments requires SPICE models of electronic components that take into account the influence of ultralow and ultrahigh ambient temperatures. However, the standard SPICE models of components in commercial versions of SPICE-like simulators provide sufficient accuracy in a limited temperature range (–60 to 150°С) and cannot be used ...

The study of the bolometer response to terahertz (THz) radiation from a double-barrier resonant tunneling diode (RTD) biased into the negative differential conductivity region of the I–V characteristic revealed that the RTD emits two pulses in a period of intrinsic self-oscillations of current. The bolometer pulse repetition rate is a multiple of the fundamental frequency ...

A theoretical formula is derived that makes it possible to establish a relationship between the speed and sensitivity of bolometers with geometric and thermophysical parameters of the receiving element and substrate. The result is confirmed by a preliminary (evaluation) experiment. The proposed thermal detectors can record and measure the radiation power of lasers and generators ...

Prospects of developing multi-element receivers for the submillimeter range (SMM) on the basis of thin-film semimetallic sensitive bolometers are considered. Electromagnetic waves of the SMM band have a high penetrating power and allow developing a thermal imager for the detection and observation of objects through various materials: fabrics, cardboard, wood, etc. The previously obtained research ...

Nafion-117 membranes in the Na+-forms with pore-intercalated mixtures of aprotic organic solvents have been obtained. Dependences of solvent uptake of the membranes versustheir pretreatment conditions and compositions of initial organic solvent mixtures are described. Ionic conductivity of the obtained membranes in the temperature range −20–50 °С is investigated using impedance spectroscopy. It is demonstrated that ionic conductivity increases with increasing solvent uptake. The highest conductivities at ...

It is shown that BSIM3 standard MOSFET SPICE model does not provide more abrupt MOSFET transconductance dependence on gate voltage at low temperature (up to –200°C) caused by mobility increase. Enhanced MOSFET macro model for low temperature is proposed which accounts for more abrupt MOSFET transconductance dependence on gate voltage. Additional nonlinear voltage-controlled voltage source ...

We have measured the electron-phonon energyrelaxation time, 𝝉𝒆𝒑𝒉, in superconducting boron-doped diamond
films grown on silicon substrate by chemical vapour deposition. The observed electron-phonon cooling times vary from 160 ns at 2.70 K to 410 ns at 1.8 K following a 𝑻!𝟐-dependence. The data are consistent with the values of 𝝉𝒆𝒑𝒉 previously reported for single-crystal boron-doped ...

Various applications in the field of terahertz technology are in urgent need of compact, wide-tunable solid-state continuous wave radiation sources with a moderate power. However, satisfactory solutions for the THz frequency range are scarce yet. Here we report on coherent radiation from a large planar array of Josephson junctions (JJs) in the frequency range between ...
