Abstract

Amino acids deposited on Cu(111) drive a separation at the two-dimensional limit between self-assembling molecules and diffusing copper atoms. During self-assembly the molecules attach to copper adatoms. This interaction freezes out copper diffusion causing the condensation of adatom islands. We observe such a separation and immobilization for eight different amino acids, suggesting the generality of this phenomenon. More details can be found in article number 1900021 by Nathan P. Guisinger, Erin V. Iski, and co-workers.
