Fe atoms were deposited on Si(111)-7×7 restructured surface, which had been covered by CH₃OH molecules. A newly formed surface is stabilized by a quasi-potential made by breaking, and adsorbed atoms or molecules can be stabilized by forming “quasi-compounds”. Then, aim to greatly enhance the magnetic properties of the memory units, nitriding experiments were implemented on the existing Fe compounds. With the in-situ observation of STM, a series of Fe₃N structures make up the newly emerged iron-nitride compounds, showing good linear characteristics. By adjusting the concentration, this study further explored its formation process and compounds models.

Fe原子沉积在已被CH ₃ OH分子覆盖的Si（111）-7×7重组表面上。新形成的表面通过断裂产生的准电势而稳定，并且吸附的原子或分子可以通过形成“准化合物”而稳定。然后，为了大大提高存储单元的磁性能，对现有的铁化合物进行了氮化实验。通过STM的现场观察，一系列Fe ₃ N结构组成了新出现的氮化铁化合物，具有良好的线性特征。通过调节浓度，本研究进一步探索了其形成过程和化合物模型。
