Observation of atomic steps on CaCO₃ crystal surface

Observation of atomic steps on CaCO 3 crystal surface 1 first-author 1 1 1 1 1 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 By using scanning polarization force microscopy, the deliquescence process and the atomic steps on the cleavage surface of CaCO 3 in air were studied in situ. Under an exposure to medium humidity (〜57%), the slow step movement has been observed.
