Encoding Information on the Excited State of a Molecular Spin Chain
The quantum states of nano-objects can drive electrical transport properties across lateral and local-probe junctions. This raises the prospect, in a solid-state device, of electrically encoding information at the quantum level using spin-flip excitations between electron spins. However, this electronic state has no defined magnetic orientation and is short-lived. Using a novel vertical nanojunction process,… Read More

Combined spin filtering actions in hybrid magnetic junctions based on organic chains covalently attached to graphene
We present a bias-controlled spin-filtering mechanism in spin-valves including a hybrid organic chain/graphene interface. Wet growth conditions of oligomeric molecular chains would usually lead, during standard CMOS-compatible fabrication processes, to the quenching of spintronics properties of metallic spin sources due to oxidation. We demonstrate by X-ray photoelectron spectroscopy that the use of a protective graphene… Read More

Negative Differential Resistance in Spin-Crossover Molecular Devices
We demonstrate, based on low-temperature scanning tunneling microscopy (STM) and spectroscopy, a pronounced negative differential resistance (NDR) in spin-crossover (SCO) molecular devices, where a FeII SCO molecule is deposited on surfaces. The STM measurements reveal that the NDR is robust with respect to substrate materials, temperature, and the number of SCO layers. This indicates that the… Read More

Open Postdoctoral position: Characterization of electronic devices This project consists in the design and characterization of sensing devices with homemade carbonaceous materials. New hybrid materials with interesting electronic properties have been obtained recently. Their potential use to elaborate active elements for devices is now the subject of thorough investigations. After a proper choice of the… Read More

Terphenylthiazole-based self-assembled monolayers on cobalt with high conductance photo-switching ratio for spintronics
Two new photo-switchable terphenylthiazole molecules are synthesized and self-assembled as monolayers on Au and on ferromagnetic Co electrodes. The electron transport properties probed by conductive atomic force microscopy in ultra-high vacuum reveal a larger conductance of the light-induced closed (c) form than for the open (o) form. We report an unprecedented conductance ratio of up… Read More
