通过对动力学模型的Monte Carlo模拟，我们证明了光致相变的效率通常可以通过使用两个组件的适当组合的超结构来大幅提高。这是由于相对接近局部不稳定性的结构块中的转化域的加速成核。本机制提供了一个一般性的指导方针，设计的光可控材料的存储和存储设备的潜在应用。
By means of Monte Carlo simulations on a kinetic model, we demonstrate that the efficiency of a photoinduced phase change can in general be enhanced drastically by using a superstructure of an appropriate combination of two components. This is due to the accelerated nucleation of converted domains in the structural blocks relatively close to local instability. The present mechanism provides a general guideline on the design of photocontrollable materials with potential applications for memory and storage devices.
