玻璃内的结构弛豫过程是众所周知的.从熔体快冷经过玻璃转变点T_g之下时,玻璃的高温准热平衡结构被冻结于低温.这种低温非平衡结构是不稳定的,会缓慢地通过弛豫过程转向晶态结构,这是一种热平衡化过程. 非晶硅不能从熔体快冷得到。而是用蒸发、溅射或等离子体分解等原子淀积方 The structural relaxation process within a glass is well-known. The high-temperature quasi-thermal equilibrium structure of a glass is frozen to a low temperature as the melt rapidly passes under the glass transition point T_g. This low-temperature unbalanced structure is unstable and slowly This is a thermal equilibrium process by the relaxation process to the crystalline structure, which can not be rapidly cooled from the melt. Instead, it is deposited by atomic deposition such as evaporation, sputtering or plasma decomposition
