SINFONIA · Selectively activated INFOrmation technology by hybrid Organic Interfaces

SINFONIA - “Selectively activated INFOrmation technology by hybrid Organic Interfaces” – is an interdisciplinary research project that envisions a technology allowing to store and transport information on the nanometer length scale and at operational frequencies in the THz regime. Such a technology will be realized through an optical manipulation of hybrid molecular/antiferromagnetic interfaces, which will enable a selective activation of information emitters and detectors. Such a selectivity will be ensured by the local nature of the hybridized electronic states that develops at the interface between an antiferromagnet (AF) and a molecular system. The main objective of SINFONIA is to exploit the hybridized states created at such interfaces to couple an external optical stimulus to the propagation of magnetic perturbations (namely spin waves) in the AF layer. This way, SINFONIA proposes a completely new approach to information technology, based on hybrid organic/inorganic low-dimensional systems. Among the breakthroughs offered by such a change of paradigm, there are: low power consumption (no electrical currents), high-frequency responses (ensured by AF materials), tunability (ensured by molecular materials), scalability and miniaturization, on account of the intrinsic low-dimensionality of our interface-based approach. SINFONIA also envisions the long-term perspective of realizing fully organic devices, thurough the development of organic AF films. The proof-of-concept of the proposed technological approach will be sought in the development of magnonics prototypical devices, such as logic gates. Magnonics is widely recognised as one of the most promising technological approaches to go beyond CMOS technology, which represents the state-of-the-art in information and communication technology.
