Abstract

We have been able to raise squares of around 2Å in height of the layered materials Bi_1.6Sb_0.4Se₃, Bi_1.9Sb_0.1Se₃ and Bi₂Se₃ by means of contact atomic force microscopy in air. By raising squares on/beneath previously produced squares, Mayan-like pyramids have been constructed, each step of the pyramid being around 2 Å in height. We neither remove matter from the surface nor produce a localized oxidation of the sample; we elevate a portion of it. When the surface is oxidized, the AFM cantilever pulls the oxide off producing holes. The raising of the squares is also possible in a nitrogen atmosphere. (C) 2000 Elsevier Science B.V.
