Secondly, the energy levels of every layer in a designed device have to be matched each other.Quantum chemical calculations were carried out in order to investigate the photoelectric performance of our target molecules.

实验表明，在阻挡层式光控载流子开关器件的设计中，要实现完全意义上的ON-OFF全开关，必须满足两个条件：一是作为光控载流子开关层的二芳基乙烯材料，必须具备足够大的开环态和闭环态之间的HOMO能级差异，在一种状态下有利于载流子的传输，在另一种状态下则可以顺利地阻挡载流子的传输；二是器件的各材料层之间的能级一定要互相匹配。

The story of the quantum revolution has been told so many times that it has become as ritualized as the stations of the cross. How Max Planck, faced with some curious observations about hot glowing objects, reluctantly proposed that light is sputtered out in packets — the quanta. How Albert Einstein , seeing deeper, realized that light must also travel that way, that its waves were also particles. How Bohr brought the graininess into the atom, with electrons hopping between orbits in quantum jumps. How Heisenberg, marooning himself on the bleak isle of Helgoland, saw that there were no orbits, that what happened inside atoms was different from anything that could be pictured by a human brain.

量子革命的故事已讲述过很多遍，就象讲述耶稣受难经过的画像一样已经仪式化，诸如：马克斯·普朗克面对炽热物体一些不寻常的观测数据，如何艰难地提出辐射是一单元一单元地射出的，这种最小的单元即能量子；爱因斯坦观察得更深刻一些，如何意识到光线也是这样运行的，光波也是粒子；玻尔如何利用量子跃迁过程中电子在轨道之间来回跳跃，来揭示原子的多微粒结构；海森堡自我流放到阴冷的赫尔戈兰岛上，如何观察到原子内部并没有轨道，其内部所发生的情况不同于人脑可想象出的任何情况。

The quantum entanglement in a system which is composed of two entangled atoms interacting with the squeezed coherent state is studied by means of the full quantum theory.
