在从稳态(2x4)到非稳态(4x2)的重构转变过程中，反射率随衬底温度的变化不连续，具有滞后周期，表现为一级转变。AS脱附过程中反射率的变化表明，由于一级跃迁亚稳态的存在，脱附速率在转变处有一个局部极小值
The reflectivity changes discontinuously at the reconstruction transition from As-stable (2x4) to In-stable (4x2) with hysteresis cycle as a function of the substrate temperature, indicating a first-order transition. The reflectivity change during As desorption shows that the desorption rate has a local minimum at the transition because of the existence of a metastable state due to the first-order transition
