Abstract
Size, dimensionality and pressure play important roles on modulating band gap (Eg) of semiconductor nanocrystals, and have attracted extensive attention in recent years. In this letter, a simple thermodynamic model is developed and the competition relation among size, dimensionality and pressure effects on Eg is discussed. The accuracy of our prediction is confirmed by the experimental data and simulation results of CdSe and ZnO nanocrystals. This model provides a new insight into the size, dimensionality and pressure effects on Eg and guides the optimal selection as design quantum devices.
