结合低能电子衍射（ＬＥＥＤ）及其消失斑点规律和扫描隧道显微镜（ＳＴＭ）手段确定了室温下甘氨酸在Ｃｕ（００１）表面能形成ｃ（２×４）和两种（２×４）吸附结构（（２×４）１和（２×４）２），并推断出在两种（２×４）结构单胞中两甘氨酸分子的羧基相对于衬底的吸附取向一致，而它们的氨基则不同．实验中还观察到ｃ（２×４）与（２×４）２结构能相互转变成窄条相互穿插共存，这说明几种吸附结构能量相近．
The results showed that glycine can form c (2 × 4) and two (2 × 4) adsorbents on Cu (001) surface at room temperature by combining LEED with its disappearing speckle and scanning tunneling microscope (STM) (2 × 4) 1 and (2 × 4) 2), and concluded that the orientation of the carboxyl groups of the two glycine molecules in the two (2 × 4) building blocks is consistent with the adsorption orientation of the substrate while their amino groups are different . It is also observed in the experiment that the structures of c (2 × 4) and (2 × 4) 2 can transform into narrow strips to co-exist with each other, indicating that the energy of several adsorption structures is similar.
