Quantum Dots: Bandgap Tuning by Using a Lattice Distortion Induced by Two Symmetries That Coexist in a Quantum Dot (Small 7/2014)
Source abstract
Abstract
A novel way to tune the bandgap in an Ag2S quantum dot (QD) system is developed by inducing a lattice-distorted region of ≈1-nm scale in a QD with rapid quenching. Accordingly, the bandgap can be controlled simply by tailoring the degree of the lattice-distortion in a QD (2.51 to 1.64 eV). As reported by H. M. Jang and co-workers on page 1300, this conceptual method can pave a new way to realize quantum effects in future QD-based applications.
