Reversible switching of Kondo resonance in a single-molecule junction

Construction and physical properties of low-dimensional structures for nanoscale electronic devices

“…In organic electronic devices, the charge transport behavior is mainly governed by the orientation and stacking of molecules. 64,71,170 In the past years, great efforts have been devoted to controlling the formation of molecular structures and their electronic properties at the single molecule level, 11,41,81 such as the growth dynamics of various functional molecules and single molecule configurations on metal surfaces with monolayer or sub-monolayer coverage, 12,13,[17][18][19][20][21][22]26,29,32,47,171,172 spindependent electronic properties of molecules with magnetic ion centers, 24,25,48,52,54,55,[60][61][62] and motion of single molecules on metal surfaces. 16,41,49,56,81 One of the key challenges for single molecule electronic devices lies in how to control their electronic transport properties through a single-molecule junction, 173 i.e.…”

“…control their electronic conduction channels by modulating the various molecular orbitals to get two stable and distinguishable electronic states for either logic or memory device applications. 10,36,52,54,58,59,61,62,174 Good control over the rotation axis and frequencies of the molecules in their selfassembled structures on a very large scale is the key requirement for construction of molecular machines like molecular rotors. 16,41,49,56,81 2.1 Construction of a single molecular rotor and its array formation on Au (111) surfaces.…”

Selectivity of Laser-Induced versus IET-Induced Carbene Formation from Methoxydiazofluorene on Ag(111)

“…Inelastic electron tunneling manipulation is a powerful tool to manipulate matter on the nanoscale. − The inelastically tunneling electrons from the STM tip induce reactions of single adsorbed molecules via the vibrational excitation of the molecules above potential energy barriers. Processes of diffusion, rotation, desorption, dissociation, and even complete reactions and reversible processes were successfully induced by inelastic effects at the single-molecule level .…”
