Descrizione

PhD fellowship in non-linear electro-plasmonics (M/F) - "Optical Memristive Memory for a modal plasmonic Arithmetic and Logic Unit.." Sintesi in italiano (traduzione automatica): L'ICB, il più grande laboratorio di fisica dell'Université Bouroggne Europe, cerca un candidato per una borsa di dottorato in elettro-plasmonica non lineare. Il candidato entrerà a far parte di un team di ricerca interdisciplinare e si occuperà di studi sulle proprietà ottiche non lineari di dispositivi logici plasmonici integrati. Le mansioni principali includono la nanofabbricazione di cavità plasmoniche e circuiti memristivi, l'analisi della risposta fotoluminescente non lineare e lo sviluppo di nuovi protocolli sperimentali. È richiesta una laurea in fisica o ingegneria fisica. Il candidato beneficerà di un ambiente collaborativo e avrà accesso a benefici per i dipendenti CNRS e supporto per lo sviluppo della carriera. La sede è a Digione, Francia. ICB is the largest physics laboratory of Université Bouroggne Europe, with 300 academic staff covering expertise in physics, chemistry and engineering. The candidate will join an interdisciplinary research team of seven academic staff with expertise in experimental and theoretical optical physics (nano-optics, nanoplasmonics, optoelectronics), nanofabrication (light, electron and ion lithography technqiues, materials deposition and patterning), nanocharacterization (SEM/TEM, near-field microscopies, ellipsometry) and physical chemistry. The PRISM team hosts an international group of post-docs, PhD students and undergraduates (currently 10) and relies heavily on two technical platforms, ARCEN (nanofabrication / nanocharacterization) and SmartLight (optics) and associated technical staff. The candidate will be trained on all relevant nanofabrication and optical set-ups facilities required to the project so as to carry out the research program autonomously. S/he will be benefiting form a collaborative environment with a broad spectrum of expertise encompassing experimental sciences, technological development and theoretical modelling. The team systematically foster participation of team members to national and international conferences. The candidate will have access to CNRS employee's benefits as well as UBE support for career development. (EU label 'HR Excellence in Research'). A new class of functional integrated and compact computing devices exploits the optoelectronic properties of noble metals such as gold and silver. The confinement and guiding of light at nanometers scales in the deep sub-wavelength regime thanks to plasmon excitations offer a unique opportunity to design new "all-optical" information transfer and processing paradigms. Our group has recently demonstrated a new concept of arithmetic and logic units (ALU, Fig. 1).1-3 The proposed work will contribute to the ANR POMMARD project, developed at ICB Dijon in collaboration with CEMES and LPCNO Toulouse, that aims at integrating the excitation of a prototypical plasmonic 2x1-bit ALU processor and its computation response. The experimental PhD fellowship (non-linear photoluminescence, nanofabrication and data analysis) aims at studying the non-linear opto-electronics properties of this new type of integrated plasmonic logic gate devices. The research work will first consist in studying the electro-memristive modulation of the non-linear optical response of the active device, which is associated to the hot electrons generated upon remote fs-pulsed excitation of the plasmonic cavity (Fig. 1c).4. Second, we will explore the reverse effect, namely the optical modulation of the conductance of an electro-plasmonic memristor nanofabricated in the direct vicinity of the processor output. When the hot carriers remotely generated in the direct vicinity of the memristor, energy transfer is expected to induce changes of its conductance state. The memristor will thus be used to readout, a posterior, this optically-triggered event, therefore realizing the first optical memristive memory integrated with the all-optical processor. The underlying physics responsible for this transduction will be thoroughly examined and modelled. At last, the project will aim at demonstrating the storage of the Boolean computation performed by the plasmonic cavity operated as an arithmetic and logic unit in such memristive memories. ---- The candidate will carry out the nanofabrication of plasmonic cavities and the memristive circuit using UV and electron-beam lithography and deposition processes in the ICB ARCEN cleanroom. S/he will characterise the non-linear photoluminescent response (NPL) and excitation efficiency of logic devices using a dedicated non-linear optical microscope. S/he will develop a new experimental setup and a protocol for memristor forming, excitation, and readout to explore the electro-plasmonic coupling regimes of the cavity and memristor.
