Description
This study about the growth of Bi on a Co-covered Cu(111) surface . Revealing that distinct surface superstructures such as √3 ×√3 R30° surface alloy and [2012] phase can be selectively fabricated by controlling the deposition parameters. The atomic arrangements and local electronic properties of these structures were characterized using scanning tunneling microscopy (STM) and spectroscopy (STS). Analysis shows that the formation of these specific phases is governed by a complex interaction between the Co interlayer thickness and the Bi coverage. This work demonstrates the high tunability and potential of the Bi/Co/Cu(111) system for atomic-scale structural design.
