Crown ethers, assembled into a regular 2D array via a chemical guesthost recognition process, have been successfully employed to trap sodium atoms on a surface, under ultra- high vacuum conditions.

S-type single alkali-adatom on graphene

Autor: Evelina A. García, S.C. Gómez Carrillo, A. Iglesias-García, Marcelo Ariel Romero

We present a theoretical study of the localized aspects of the alkali-metal atoms (Li, Na, K) interacting with graphene. We use an ab-initio calculation of the Hamiltonian parameters where the chemical properties of the interacting atoms (alkali and
