According to Fourier's law, a temperature difference across material results in linear profile and thermal conductance that decreases inversely proportional the system length. These are hallmarks of diffusive heat flow. Here, we report flow ultrathin (25 nm) GaP nanowires absence gradient within wire find is independent observations deviate from law direct proof ballistic flow, persisting for lengths up at least 15 μm room temperature. When doubling diameter, remarkably sudden transition...
A 6.1-MV, 0.79-MA laser-triggered gas switch (LTGS) is used to synchronize the 36 modules of $Z$ machine at Sandia National Laboratories. Each module includes one switch, which serves as last command-fired module, and hence determine time each electrically closes relative other modules. The $\ensuremath{\sim}81\mathrm{\text{\ensuremath{-}}}\mathrm{cm}$ in length, $\ensuremath{\sim}45\mathrm{\text{\ensuremath{-}}}\mathrm{cm}$ diameter, immersed mineral oil. outer envelope consists six...
In many industrial processes, a large proportion of energy is lost in the form heat. Thermoelectric generators can convert this waste heat into electricity by means Seebeck effect. However, use thermoelectric practical applications on an scale limited part because electrical, thermal, and mechanical bonding contacts between semiconductor materials metal electrodes current designs are not capable withstanding thermal-mechanical stress alloying metal–semiconductor interface when exposed to...
Here we present the realization of efficient and sustainable silicon‐based thermoelectric materials from nanoparticles. We employ a gas phase synthesis for nanoparticles which is capable producing doped silicon (Si) nanoparticles, alloy germanium (Ge), Si x Ge 1– , composites with embedded metal silicide precipitation phases. Hence, so‐called “nanoparticle in alloy” approach, theoretically proposed literature, forms guideline material development. For bulk samples, current‐activated...
This note describes the construction and engineering of a high precision Harman set-up for metrology thermoelectric figure merit (ZT) modules materials based on steady state AC DC measurements. The technique presented in this article has resolution milli-ZT it does not employ lock-in amplifiers or bridges; rather, is developed to avoid typical complications experienced systems. By one-time reference measurements best operation point system chosen, minimizing effects capacitive loads due signals.
Increasing energy demand and depleting fossil fuels make it imperative to shift more efficient sources. Thermoelectric materials can convert waste heat into electrical by means of the Thermopower or Seebeck effect. Nanowires are promising candidates increase efficiency thermo-electric conversion because their low dimensionality is predicted effect due confinement charge carriers decrease thermal conductivity boundary scattering phonons. The characterized coefficient which describes output...
