Toward the Ultimate Limit: Elemental Metals in One Dimension
Mohammad Bagheri, Kameyab Raza Abidi, Sushree Sarita Sahoo +2
Low-dimensional materials exhibit extraordinary properties that make them promising candidates for advanced technologies. Although they have been investigated extensively, most of…
Optimizing density-functional simulations for two-dimensional metals
Kameyab Raza Abidi, Pekka Koskinen
Unlike covalent two-dimensional (2D) materials like graphene, 2D metals have non-layered structures due to their non-directional, metallic bonding. While experiments on 2D metals a…
Limits of Lateral Expansion in Two-Dimensional Materials with Line Defects
Pekka Koskinen
The flexibility of two-dimensional (2D) materials enables static and dynamic ripples that are known to cause lateral contraction, shrinking of the material boundary. However, the l…
Rippling of two-dimensional materials by line defects
Topi Kähärä, Pekka Koskinen
Two-dimensional materials and their mechanical properties are known to be profoundly affected by rippling deformations. However, although ripples are fairly well understood, less i…
Free-standing 2D metals from binary metal alloys
Janne Nevalaita, Pekka Koskinen
Recent experiment demonstrated the formation of free-standing Au monolayers by exposing Au-Ag alloy to electron beam irradiation. Inspired by this discovery, we used semi-empirical…
Stability limits of elemental 2D metals in graphene pores
Janne Nevalaita, Pekka Koskinen
Two-dimensional (2D) materials can be used as stabilizing templates for exotic nanostructures, including pore-stabilized, free-standing patches of elemental metal monolayers. Altho…
