Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201470111-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A novel way of tuning the bandgap in a quantum dot (QD) is by lattice distortions, using 4 nm CdS QDs grown on a TiO₂ particle for example. The bandgap tuning (from 2.74 eV to 2.49 eV) of a CdS QD is achieved by H. M. Jang and co‐workers by suitably adjusting the degree of lattice distortion in the QD via manipulation of the tensile residual stresses. As reported on page 3678, the present methodology will potentially pave a way to explore quantum effects in various QD‐based applications. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1c9n2782" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
