TE-BASED THERMOELECTRIC MATERIAL HAVING COMPLEX CRYSTAL STRUCTURE BY ADDITION OF INTERSTITIAL DOPANT
Publication number: 20150372212Abstract: This invention relates to a Te-based thermoelectric material having stacking faults by addition of an interstitial dopant, including unit cells configured such that A-B-A-C-A elements are stacked to five layers, in which A element of a terminal of a unit cell and A element of a terminal of another unit cell are repeatedly stacked by a van der Waals interaction, wherein an interstitial element as the dopant is located at an interstitial position between the repeatedly stacked A elements adjacent to each other, thus generating stacking faults of the repeatedly stacked unit cells to thereby form a twin as well as a complex crystal structure different from the unit cells (where A is Te or Se, B is Bi or Sb, and C is Bi or Sb).Type: ApplicationFiled: August 29, 2014Publication date: December 24, 2015Inventors: Su Dong Park, Bong Seo Kim, Bok Ki Min, Min Wook Oh, Jae Ki Lee, Hee Woong Lee, Gi Jeong Kong -
Patent number: 8894792Abstract: Disclosed herein are a method for manufacturing a functional material for use in various industrial fields in which anisotropy or physical properties change according to height may be utilized, as well as a functional material manufactured thereby. The method includes the steps of: (1) mixing powders composed of the components of the functional material with a binder to prepare a mixed paste; (2) coating the mixed paste on a substrate, and then separating the coated material from the substrate, thus preparing a slice; (3) repeating step (2) to prepare a plurality of slices, and stacking the slices in a mold; and (4) pressing the stacked slices at a predetermined temperature and pressure. A multifunctional material, such as an anisotropic material having physical properties which change according to the direction of material, or a material having physical properties which change in a graduated manner according to height, may be manufactured in a simple and economical manner.Type: GrantFiled: December 26, 2008Date of Patent: November 25, 2014Assignee: Korea Electrotechnology Research InstituteInventors: Su Dong Park, Hee Woong Lee, Bong Seo Kim, Min Wook Oh
