通过引入一个新的模型，研究了sc晶体（001）面上[100]台阶的非平衡结构，该模型将台阶上的吸附原子和空位密度作为独立变量，并考虑了扭结沿着台阶的运动。该步骤的结构变化被发现是一个弛豫型的弛豫时间是温度和过饱和度的函数。在低温和低过饱和度的情况下，得到了扭结的稳态密度的近似公式。
The non-equilibrium structure of a [100]step on a (001) surface of a sc crystal is studied by introducing a new model in which densities of adatoms and vacancies on the step are treated as independent variables and the motion of kinks along the step is taken into account. The structural change of the step is found to be of a relaxational type with a relaxation time that is a function of temperature and degree of supersaturation. An approximate formula for the steady-state density of kinks for the case of low temperatures and low supersaturations is obtained.
