Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgj410gr6c" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />We have demonstrated a new method for synthesizing monodisperse ultra-small PbSe NRs with the diameter approaching 2 nm (<italic>E</italic>_g &gt; 1.2 eV). The PbSe NRs show n-type properties and high electron mobility as measured by using field-effect transistors. The PbSe NRs with narrow diameters are used for the first time in solar cells and their improved efficiency is demonstrated when used together with QDs.</p> </abstract>
