The presented studies of resistivity (ρ), thermal conductivity (κ) and specific heat (C) at low temperature 1.8−7 K in magnetic field up to 90 kOe made it possible to detect for the first time the exponential field dependences ρ(H), κ −1(H), C(H) ∼ exp(−μeffH/kBT) of the charge transport and thermal characteristics in the so-called antiferroquadrupole (AFQ) ...

Nickel-doped off-stoichiometric bornite Cu5–xNixFeS3.71 0 ≤ x ≤ 1 nanoparticles were synthesized by high-energy mechanical alloying (MA) and subsequent annealing at 653 K for 1 h. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) of the annealed powders revealed low-orthorhombic bornite as the main phase with a minor amount (< 2%) of digenite as the second phase. XRD analysis, scanning electron microscopy ...

Carbon nanowall films with different thicknesses have been obtained by chemical deposition from a gas phase in a dc discharge. The thermal conductivity of the resulting structures has been measured for the first time using the 3ω method in the temperature range of 280–310 K. It has been shown that the thermal conductivity of walls ...

The work is devoted to evaluation of the thermal conductivity of composites based on asphaltenes and paraffin as a phase change material. Asphaltenes with different structural characteristics, obtained by chemical modification and fractionation were used to improve the heat conductivity of paraffin. Modification of asphaltenes with sulfuric acid and oleum made it possible to obtain ...

Theoretical and experimental data on the eff ect of additions of micro- and nanosized solid particles on the thermal conductivity of liquid media (nanofl uids) are considered. According to theoretical calculations, a manifold increase in the thermal conductivity is possible only for resting media in which percolation structures are formed from the modifi er nanoparticles, ...

Thermal properties of sediments in the East Siberian Arctic Seas: A case study in the Buor-Khaya Bay
Chuvilin E., Bukhanov B., Grebenkin S. et al., Marine and Petroleum Geology 2021 Vol. 123 Article 104672
The temperature and thermal properties of shelf sediments from the East Siberian, Laptev, and Kara Seas were determined from field investigations. The sediments were in an unfrozen cryotic state (ice-free) and showed negative temperatures, ranging from −1.0 to −1.4 °C. These temperatures imply the presence of widespread subsea permafrost from the shelf to the continental slope ...

We examine the role of a silicon-based amorphous insulating substrate in the thermal relaxation in thin NbN, InOx, and Au/Ni films at temperatures above 5 K. The samples studied consist of metal bridges on an amorphous insulating layer lying on or suspended above a crystalline substrate. Noise thermometry is used to measure the electron temperature Te of the films as a ...

SOI MOSFETs have the worst properties of heat removal from an active region, which negatively
affects the reliability and efficiency of integrated circuits. Using TCAD modeling, we investigate the self-heating
effect in the following structures of deeply submicron MOSFETs with different configurations of buried
oxide: traditional bulk MOSFET, SOI structure, SELBOX structure, partial SOI structure, thin-BOX SOI
structure, UTBB ...

In this work self-heating effect in SOI MOSFETs with various configuration of buried oxide was investigated using TCAD modeling. The basically electro-thermal transport model built-in to Sentaurus Synopsys tool was complemented by the set of new models for the temperature-dependent physical parameters: thermal conductivities λSi(T), λSiO2(T); oxide and trapped charge densities Nox(T), Nit(T) and others ...
