Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201300599-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>An effective approach to enhance the thermoelectric performance (ZT) of polycrystalline In₄Se₃ based samples</bold> by crystallographic and microstructural engineering is proposed and demonstrated. Cu intercalation, Br substitution at selenium sites, and incorporation of dispersed hierarchical nanoparticles are discussed. An improved ZT of 1.1 at 723 K is achieved in CuBr₂ doped In₄Se_2.5. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sm3jjsk" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
