Simple polishing and relatively low temperature annealing procedures for preparing atomically flat terraced surfaces of various single-crystal TiO2 polymorphs are described. Anatase (101), anatase (001), rutile (100), rutile (110), and brookite (111) surfaces could all be prepared with a terraced surface structure as revealed in AFM images. The rutile (100) and (110) and anatase (101) surfaces were also shown to produce acceptable LEED patterns immediately upon insertion into a UHV system without the usual sputter and anneal cycles.
本文描述了用于制备各种单晶TiO2多晶型原子级平整梯田状表面的简单抛光和相对低温退火程序。如原子力显微镜（AFM）图像所示，锐钛矿（101）、锐钛矿（001）、金红石（100）、金红石（110）和板钛矿（111）表面均可以制备出具有梯田状表面结构的表面。金红石（100）和（110）以及锐钛矿（101）表面在插入超高真空（UHV）系统后，无需通常的溅射和退火循环，即可立即产生可接受的低能电子衍射（LEED）图案。
