The distribution of strain field plays an important role in deciding the physical properties of nanocrystals. The growth strain of Ge/GeO2 core/shell nanoparticles embedded in a regular array of Al2O3 nanoparticles and its resulting effect on the optical properties are investigated. Two-dimensional...
