Offer Description
Imagine your computer starting instantly and performing logic operations at the speed of light without overheating. Although this sounds as a science fiction today, it can be become reality soon, by replacing electrical computing with optical computing. To make this happen the photonic processors must be realized. The building blocks for such processors are photonic devices capable to modulate signal light beam. In the same way as electrical transistor revolutionized electronics, the discovery of photonic transistor should open a whole new era of photonic devices for superior data processing possibilities. Your PhD work will help to advance the area of optical computing by developing new type of photonic devices uniting experimental studies in the area of ferroelectricity (FE) and photovoltaics (PV). At certain conditions the FE material under light can show a complex response including the both light-induced charge generation and depolarization processes. Combining unique electronic properties of the 2D materials [1] with such FE compounds can prone to electro-optical and even all-optical atomic scale devices control. While the electrical control has already been demonstrated in such heterostructures for the both bulk [2] and surface [3] configurations the optical one is much less studied. The purely optical approach, however, represents a promising research direction as recently reported [4,5]. At certain conditions the FE material under light can show both light-induced charge generation and relaxation processes. Such interplay can lead to both transient and remanent effects due to intrinsic electric field. The task of PhD student will be to prepare 2D structures and heterostructures over the multifunctional ferroelectric substrates using nanofabrication facilities in a clean room environment of the Institute. The electrical, optical (in some cases magnetic) measurements will be then performed by the candidate according to the objectives. The candidate should have an experience in research lab work, good skills in spoken and written French or English and sufficient knowledge of material science. Experience in a clean room environment is an advantage.
