Artificial relativistic molecules

Abstract: We fabricate artificial molecules composed of heavy atom lead on a van der Waals crystal. Pb atoms templated on a honeycomb charge-order superstructure of IrTe2 form clusters ranging from dimers to heptamers including benzene-shaped ring hexamers. Tunneling spectroscopy and electronic structure calculations reveal the formation of unusual relativistic molecular orbitals within the clusters. The spin-orbit coupling is essential both in forming such Dirac electronic states and stabilizing the artificial molecule… Show more

“…With respect to studying electronic properties of extended systems, two complementary approaches have been used. The first approach is based on coupling localized states of either adatoms, vacancies or dangling bonds, [16][17][18][19][20][21][22][23]. By positioning such species with atomic scale precision, artificial electronic molecules or lattices can be created and their electronic structure studied.…”

“…In recent years, there have been efforts to represent the observation of movements inside materials using Dirac electric states [50] as well as to use relativistic methods to understand atomic and molecular structure [51]. There have also been efforts to provide covariant formulation of the electrodynamics of nonlinear media [52].…”
