PHEMTRONICS is a H2020 FETOPEN Project addressing Active Optical Phase-Change Plasmonic Transdimensional Systems EnablingFemtojoule and Femtosecond Extreme Broadband Adaptive Reconfigurable Devices.

PHEMTRONICS has the ambitious vision of translating forefront knowledge in phase-transformation dynamics of“light controllable active matter with reconfigurable and interactively tunable dynamical properties” into broadbandreconfigurable and adaptive devices by developing a radically novel transdimensional materials platform that isintrinsically phase change, low-loss plasmonic and electronically topological. The photon-electron-phonon couplingwill enable a new technology paradigm of adaptive optical signal processing with key metrics of the “femtosecond-scale switching time”, “ultralow power of femtojoule/bit” and “microwave-to-optical frequencies” broadbandcapability required for reliable multibit operationsTo do so PHEMTRONICS will (i) develop a novel platform of eco-sustainable non-toxic phase-changetransdimensional materials with a large pool of structural motifs, accessible close to room temperature; (ii) pioneera programmable mixed-mode plasmon-opto-electrical machine, actuated with novel active phase-change low-lossplasmonic nanoantennas, exploiting mechanisms of dynamical amplification of phonons by plasmons to achievemode-selective enhancement (iii) master beyond-equilibrium phase-transformations through predictive models toguide reconfigurability of devicesWe will deliver innovative ultrafast light induced phase-change switches, dynamically reconfigurable nanoantennasand adaptive switchable multiple-band detectors surpassing the current paradigms of speed, energy and frequenciesPHEMTRONICS interdisciplinary team covering the whole value chain, from a novel class of plasmonic phase-change materials, to fabrication, design, modelling tools and integration to new device architectures, will herald anew era in the fields of mobile communications, optical computing, ultrafast athermal switching for neuromorphiccomputation, tuneable nanopixel displays, creating new markets and reinforcing the leadership of European researchand industrial players.
