The formation of molecular fibres is often hampered by defects such as step edges, which act as nucleation sites. Here, we present a concept of how exposure of the support to oxygen or even air disables the formation of such defect-driven fibres.
Electrochemical carbon dioxide reduction reaction (CO2RR) to chemicals can store renewable electricity and simultaneously control global warming. Albeit inexpensive copper electro-catalyzing CO2 to hydrocarbons at reasonable rates, it suffers from...
For the first time structural changes on Si(111) surface have been visualized directly during Sn deposition at Т=200–800°С. Si atoms detached from step edges were founded to participate in (√3×√3) structure formation at T>650°С. Electromigration influence on terraces filling of Si(111)-(√3×√3) surface by “1×1”-Sn phase was shown. Sn atoms on Si(111)- (√3×√3) surface have positive effective charge.
