Quantum Dots: Bandgap Tuning with Thermal Residual Stresses Induced in a Quantum Dot (Small 18/2014)
Source abstract
Abstract
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.
