Although semiconductor wires exhibit unique properties that would benefit a range of devices, implementation of as-grown wires in a device brings challenges, in particular, for those that require large volume (e.g. thermoelectric (TE) devices). Therefore, a post-growth assembly of sub-micrometer-scale wires into a centimeter-scale structure would open new module architecture. In this paper, TE devices in the form of pellet (~1cm diameter) made of aggregated silicon (Si) wires will be described. Numerous Si wires were assembled into a 3D network with dimensions defined by a quartz ampule. Power generation was demonstrated at operational temperatures ~80°C and the performance was generalized for higher operational temperatures ~800°C.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
