Thermoelectricity for crystallographic anisotropy controlled Bi–Te based alloys and p–n modules

Temperature distribution for electrically conductive and non-conductive materials during Field Assisted Sintering (FAST)

“…In 2007, more than 470 papers were published. The research includes all fields of materials starting from intermetallics, 1-2 thermoelectrics, [3][4] ceramics and composites, 5-7 functional graded materials [8][9] and hard metals. [10][11] There are just a few articles existing who mainly deal with investigations on the process itself.…”

Crystallographic Orientation Analysis on Calcium Cobaltite Ceramic Grains Textured by Reactive‐Templated Grain Growth

“…8,12 However, the electrical conductivities of the textured CCO ceramics were greatly varied depending on the microstructure of each specimen having similar Lotgering's degree of orientation. 17,18 The EBSP technique utilizes Kikuchi lines and bands for determining the crystallographic orientations. These XRD methods give the statistical average distribution of a specific crystalline plane in polycrystalline materials.…”

Developments in semiconductor thermoelectric materials

“…This bonding becomes a cleavage plane that leads to strength reduction in the single crystal. To overcome the disadvantages presented by single crystals, many synthetic methods were employed to obtain Bi 2 Te 3 -based alloy bulks with higher mechanical strength and good thermoelectric properties; these methods include the Bridgman-Stockbarger method [20], equal channel angular pressing [21], hot pressing [22], hot extrusion [23,24], shear extrusion [25], and physical vapor deposition [26]. Using a two-step spark plasma sintering technique, researchers prepared textured n-type Bi 2 Te 3 with enhanced thermoelectric and mechanical properties; the authors indicated that controlling texture effectively improved the thermoelectric and mechanical properties of Bi 2 Te 3 -based materials [27].…”
