Patent number: 11796488Abstract: Methods for determining desired doping conditions for a semiconducting single-walled carbon nanotube (s-SWCNT) are provided. One exemplary method includes doping each of a plurality of s-SWCNT networks under a respective set of doping conditions; determining a thermoelectric (TE) power factor as a function of a fractional bleach of an absorption spectrum for the plurality of s-SWCNT networks doped under the respective sets of doping conditions; and using the function to identify one of the TE power factors within a range of the fractional bleach of the absorption spectrum. The identified TE power factor corresponds to the desired doping conditions.Type: GrantFiled: January 15, 2021Date of Patent: October 24, 2023Assignee: Alliance for Sustainable Energy, LLCInventors: Azure Dee Avery, Jeffrey Lee Blackburn, Andrew John Ferguson, Taylor Christie Julia Aubry-Komin
