日本长野县(?)泽地区所产的赤铁矿晶体的{0001}面上出现的螺旋状生长台阶与其他产区的多角形平滑台阶不同,即:生长台阶前沿具有波状起伏特征(砂川,1979),当生长台阶厚度较薄时,起伏波长较短,随着由薄层迭积所致的台阶厚度增加,其波长也随之变长.然而,产主上述现象的原因至今尚未搞清楚,是由于温度上升所致或是与生长动力学有关的动力学粗糙化所致,或者是由于形态稳定性的变化所致?针对这个问题,作者用12NHCI对晶体表面进行腐蚀,根据对浸蚀后特征的观察,查明了台阶粗糙化的原因.
The spiral growth step on the {0001} plane of hematite crystals produced in the Zee area of Nagano prefecture in Japan is different from the polygonal smooth steps of other producing areas, ie, the wavy undulating features at the front of the growth step (sand, 1979), when the growth step thickness is thinner, the wavelength of the ripple is shorter and the wavelength becomes longer as the thickness of the step due to the lamination is increased. However, the reason for the above phenomenon has not yet been clarified , Is due to the temperature rise due to kinetics or related to the dynamics of the dynamic roughening, or due to the stability of the morphological changes? To address this issue, the author of 12NHCI crystal surface corrosion, according to the erosion After the observation of the characteristics of the stairs to find out the reasons for the roughening.
