AbstractThe mechanism and kinetics of the ultrafast hydrogen failure of thermoelectric materials in electrochemical cells during water electrolysis (T = 300 K) are studied. The effect is explained by the “gas” failure caused by the penetration of nonequilibrium hydrogen into the material volume followed by molization (2H+ + 2e– → H2) at lattice def...

AbstractA mathematical model is proposed for determining the quality of applying a heat-conducting compound, and simulation results are presented. The model is based on the theory of heat transfer in a solid. The model has been verified using experimental data obtained by measuring the temperature at the points of contact of two bodies using thermo...

A broadband graphene-on-Si3N4-membrane photodetector for the visible-IR spectral range is realised by simple lithography and deposition techniques. Photo-current is produced upon illumination due to presence of the build-in potential between dissimilar metal electrodes on graphene as a result of charge transfer. The sensitivity of the photo-detecto...
In the physics of condensed matter, quantum critical phenomena and unconventional superconductivity are two major themes. In electron doped cuprates, the low upper critical field allows one to study the putative QCP at low temperature and to understand its connection to the long standing problem of the origin of the high Tc superconductivity. Here ...

The vibrational excitation related transport properties of a manganese phthalocyanine molecule suspended between the tip of a scanning tunneling microsope (STM) and a surface are investigated by combining the local manipulation capabilities of the STM with inelastic electron tunneling spectroscopy. By attachment of the molecule to the probe tip, th...
The dependence of magnetic and thermal transport properties on charge states of Mn and Co in LaMnO3 and LaCoO3, respectively, has motivated to perform a systematic study in the La0.95Sr0.05Co1-xMnxO3 (0.00

The Seebeck effect is derived within the thermodynamics of irreversible processes when the generalized forces contain the magnetic term M ∇ B . This term appears in the formalism when the magnetic field is treated as a state variable. Two subsystems are considered, one representing atomic magnetic moments, and the other, mobile charges carrying a m...

Ab-initio calculations using the full potential linearized augmented plane-wave technique and the semi-classical Boltzmann theory are used to study thermoelectric properties of unstrained SnS and at 1%, 2% and 3% applied biaxial tensile (BT) strain. The studies are carried out at 800 K for p-type and n-type carriers. For an increase in BT strain, l...

Thermoelectric (TE) energy conversion with nontraditional organic materials is promising in wearable electronics and roll-to-roll manufacturing because of mechanical flexibility, lightweight, and easy processing. Although typical organic materials have a benefit of low thermal conductivity that creates a large temperature gradient, relatively small...

Organic conductors are being evaluated for potential use in waste heat recovery through lightweight and flexible thermoelectric generators manufactured using cost-effective printing processes. Assessment of the potentiality of organic materials in real devices still requires a deeper understanding of the physics behind their thermoelectric properti...
