Scalable Nernst thermoelectric power using a coiled galfenol wire

Hot-wire deposition of amorphous and microcrystalline silicon using different gas excitations by a coiled filament

Microcrystalline silicon (mc-Si:H) and amorphous silicon (a-Si:H) films were deposited using a hot-wire CVD (HWCVD) system that employs a coiled filament. Process gasses, H and Si H , could be directed into the deposition chamber via different 2 2 6 gas inlets, either through a coiled filament for efficient dissociation or into the chamber away from the filament, but near the substrates. We fou...

Miniaturized Thermoelectric Power Sources

Advanced thermoelectric microdevices integrated into thermal management packages and low power, electrical power source systems are of interest for a variety of space and terrestrial applications. By making use of macroscopic film technology, microgenerators operating across relatively small temperature differences can be conceptualized for a variety of high heat flux or low heat flux heat sour...

Thermoelectric Power in Graphene

Recent years have witnessed considerable interest devoted to the electronic properties of graphene [1-3]. Graphene, a one-atom-thick sheet of carbon atoms arranged in a honeycomb crystal, exhibits unique properties like high thermal conductivity, high electron mobility and optical transparency, and has the potential for use in nano-electronic and optoelectronic devices. With the size of these d...

Fabrication and thermoelectric properties of eco-friendly silicides for thermoelectric power generation using waste heat

Thermoelectric Power Measurements in Wustite

High temperature thermoelectric power measurements were performed on single crystal samples of wustite in equilibrium with a carbon dioxidecarbon monoxide atmosphere. These measurements were made using a "heat pulse" technique which allowed the thermoelectric power of a sample to be determined in a matter of seconds. The short time required for this measurement precluded any possibility of ioni...
