Abstract:
A semiconductor thermoelectric device comprising:a doped layer of semiconductor material having a first side and a second side and having contiguous regions, said doped layer being polysilicon and being p-doped and n-doped region-by-region in alternating fashion for positive and negative electrical conductivities;a first thermally conductive layer arranged on said first side of said doped layer in relation to a direction perpendicular to a planar extension of said doped layer;a second thermally conductive layer arranged on said second side to said doped layer in relation to a direction perpendicular to a planar extension of said doped layer;said doped layer being in thermal contact with said first thermally conductive layer and being thermally insulated from said second thermally conductive layer at points of said doped layer at which, in a predetermined direction, there are junctions from said p-doped regions to said n-doped regions;said doped layer being in thermal contact with said second thermally conductive layer and being thermally insulated from said first thermally conductive layer at points of said doped layer at which, in a predetermined direction, there are junctions from said n-doped regions to said p-doped regions; andcontacts for electrical connection applied to said doped layer.
