摘要:

我们报道了在W(110)衬底上成功地稳定了具有(110)取向的厚块状、畸变的$α$ -Mn薄膜。观察到的$(3\times3)$ overstructure的Mn膜相对于原来的W(110)低能电子衍射图案是一致的提出的结构模型。支持密度泛函总能量计算的可能性,以稳定这样的假晶锰膜。稳定的$α$ -Mn(110)膜的角分辨光电子能谱显示出与大的晶胞一致的价带电子态的弱分散。

英文摘要:

We report the successful stabilization of a thick bulk-like, distorted $α$-Mn film with (110) orientation on a W(110) substrate. The observed $(3\times3)$ overstructure for the Mn film with respect to the original W(110) low-energy electron diffraction pattern is consistent with the presented structure model. The possibility to stabilize such a pseudomorphic Mn film is supported by density functional total energy calculations. Angle-resolved photoemission spectra of the stabilized $α$-Mn(110) film show weak dispersions of the valence band electronic states in accordance with the large unit cell.
