Magnetic Tunnel Junctions with Self-Assembled Molecules
Wenyong Wang, Curt A. Richter
Molecular electronic devices with spin-dependent tunneling (SDT) transport behavior offer an innovative and extremely enticing direction towards spin electronics, both from fundamental and technological points of view. In this work, such molecular magnetic tunnel junctions are fabricated and inelastic electron tunneling spectroscopy (IETS) provides the unambiguous experimental evidence of the existence of molecular species in the devices. Tunneling spectroscopy are also used to investigate the spin-polarized inelastic tunneling processes in the molecular device for the first time, and show that inelastic scattering due to molecular vibrations, instead of magnon excitations, is likely the main cause of the observed JMR bias-dependence.
