RESEARCH FOCUS

ACMOL is embedded in the field of molecular spin electronics (molecular spintronics) which aims at fabricating novel devices exploiting both the electron spin and the electron charge of the molecule for information processing.
The ACMOL motivation for a long-term vision is to contribute to the technological progress that our society demands. The main aspects are summarized as follows: i) nonvolatility of the spintronics devices ii) increased data processing speed and iii) increased integration densities. All these aspects are actual key concerns of our society, since the increasing interest in miniaturizing electronic devices having increased speed and high-density circuits is currently hindered by the growing limitations that current metal-oxide semiconductor (CMOS) technology faces.

ACMOL objectives Milestones (MS)

1. Design, synthesis and characterization of novel magnetic and electro-active compounds, derivatives of polychlorinated triphenylmethyl (TM) radicals and tetrathiafulvalenes (TTFs) molecules, which guarantee long-term stability and excellent reversibility at room temperature and which have appropriate anchoring groups for sp2-carbon based electrodes modification and self-assembling.

2. Fabrication of nano-spaced few layers (FL)-graphene electrodes, for mechanically controlled break junction (MCBJ) and for single molecular transistor (SMT), the latest combined with ferromagnetic materials.

3. Establishment of the fundamental aspects of electron transport through TM radicals and TTF molecules in two- and three-terminal devices and establishment of the relationship between the structural functionality of the molecular junctions and their electronic response.

4. Description of electronic transport in Kondo and weak-coupling regimes through a theoretical scheme that combines first-principles and many-body methods.

5. Measurement of tunnelling magnetoresistance (TMR) in Flgraphene nano-sized gap at room temperature and measurement of spin-injection through the target molecules.

6. Manipulation of the spin-polarized current by switching the magnetic state of the molecular nano-junction. Proof-of-concept of the switchable spin-polarizer.
