Thermoelectric Power Factor of Ultra-Narrow Silicon Nanowires
The thermoelectric performance of materials is determined by the figure of merit ZT=σS2/(κe+κl), where σ is the electrical conductivity, S is the Seebeck coefficient and κe and κl are the electronic and lattice contributions to the thermal conductivity, respectively. The interrelation between these quantities has traditionally kept ZT low, around unity. Nanomaterials have recently attracted sig...
متن کاملThermoelectric Power Factor of Narrow Silicon Nanowires from Atomistic Considerations
Silicon nanowires (NWs) of small diameters have attracted significant attention as efficient thermoelectric materials since the work of Hicks and Dresselhaus [1], who pointed out that low dimensionality can be beneficial to the Seebeck coefficient. The recent results of Boukai et al. [2], and Hochbaum et al. [3] showed that it is indeed possible to achieve ZT~0.5 at room temperature in Si NWs o...
متن کاملThermoelectric Power Factor of Low Dimensional Silicon Nanowires
We analyze the thermoelectric power factor in ultra-narrow low-dimensional silicon nanowires (NWs) by employing atomistic considerations for the electronic structures and linearized Boltzmann transport theory. We consider different transport orientations and both n-type and p-type NWs. We show that the NW properties are highly anisotropic, especially for p-type, and as the diameter is reduced f...
متن کاملAn Air-Breathing, Portable Thermoelectric Power Generator Based on a Microfabricated Silicon Combustor
The global consumer demand for portable electronic devices is increasing. The emphasis on reducing size and weight has put increased pressure on the energy and power densities of available power storage and generation options, which have been dominated by batteries. The energy densities of many hydrocarbon fuels exceed those of conventional batteries by several orders of magnitude, and this gap...
متن کاملMulticolored vertical silicon nanowires.
We demonstrate that vertical silicon nanowires take on a surprising variety of colors covering the entire visible spectrum, in marked contrast to the gray color of bulk silicon. This effect is readily observable by bright-field microscopy, or even to the naked eye. The reflection spectra of the nanowires each show a dip whose position depends on the nanowire radii. We compare the experimental d...
