Artur Movsesyan from CINaM, CPJ AMUTech, will give a talk entitled “Plasmonic nanosystems: driving force of optical chirality, photochemistry and microfluidic” on Friday March 27th at 09:30 a.m. in our Pierre Cotton’s room.
Metal nanostructures, beyond functoning as efficient absorbers and scatterers of light, play an important role in applications including sensing, chirality, and enhanced spectroscopies One of their distinctive features is their ability to efficiently convert light, into different forms of energy. Under optical excitations, these metal structures experience the generation of carriers, including high-energy (hot) electrons, which can dissipate into thermal energy. The versatile utility of hot carriers extends to applications in photochemistry, photovoltaics and thermofluidic.
During this seminar, he will discuss the optical, optoelectronic, and photothermal characteristics of plasmonic nanostructures, superstructures, and metasurfaces. He will introduce their applications in improving photoemission processes, boosting photochemistry, harnessing optical chirality, and driving a microfluidic system. Special emphasis will be placed on topics such as chiral laIces, near-field chirality, the role of hot carriers and the effects of photothermal interactions. He will finalize the seminar by introducing the project that he is going to pursue “Controlling hot-electron and heat sites in 2D nanophotonic metasurface” and envisioned collaborations within the AMU Tech and beyond.
