演講摘要：

Thermoelectric generators (TEGs) using thermoelectric (TE) materials are attractive because they do not require moving parts and can generate electricity silently by using a temperature gradient. A TEG module is the -shaped assembly of alternating p-type and n-type TE materials, which are connected electrically in series and thermally in parallel. Single-walled carbon nanotubes (SWCNTs) are promising TE materials because of their high electrical conductivity and Seebeck coefficient. An advantage of using SWCNTs for TEGs is their bendability, which imparts flexibility or even stretchability to the device. Therefore, a TEG module that can cover the surface of heat sources and take complete advantage of ubiquitous waste heat, such as body heat, has been the target of the CNT-based TEG. Recent studies revealed that the zT of SWCNT-based materials is still lower than 0.3, thus, a large integration of the p- and n-type CNT legs is vital to achieve considerable power generation. To construct a TEG employing SWCNTs, the development of n-type regions within a single piece of p-type SWCNTs has gained interest, offering a seamless TEG structure without the need for metal electrodes to bridge the p- and n-type regions.[1-3] To achieve p/n patterns with high special resolution, we developed patterning methods including thermal deposition of n-dopant precursor [4] and photoinduced doping [5, 6] as the substitutes for traditional drop casting method. In this seminar, detail procedure of these techniques as well as the principle of air-stable n-doping of SWCNT will be explained.
