Halide perovskites is an emerging class of high-performance semiconductors which operate in the visible and infrared energy range. These old materials were recently popularized owing to the development of efficient photovoltaic devices, spearheaded by CH3NH3PbI3. Starting from the modest 3% in 2009, halide perovskites can now consistently produce competitive power-conversion-efficiencies (PCE > 20%), thus representing one of the fastest developing solar cell technologies known to date. The remarkable physical properties of the halide perovskites stem from their unique electronic structure, which lends the semiconductors beneficial characteristics, such as high absorption coefficients and charge-carrier mobilities.
In this talk, the compositional space of the halide perovskites, AMX3, (A+ = Cs, CH3NH3, HC(NH2)2); (M2+ = Ge, Sn, Pb); (X- = Cl, Br, I) will be outlined and the structural chemistry of the materials will be detailed. The central role of the crystal structure, where small changes can significantly alter the optical, electrical and electronic properties of the perovskites will be discussed and the synthetic chemistry concepts that can “control” these subtle modifications will be elaborated. Furthermore, following the dimensional reduction principle, the synthesis and properties of low dimensional systems such as “hollow” perovskites, two dimensional perovskites and perovskite polytypes will be discussed.

Position Description
Optical Memristors are disruptive photonic elements which have attracted significant attention during the last few years, while offering unique switching and memory-like characteristics, for driving the future optical networks and sensing systems. The FORTH-SYNERGY project Optical Memristors, based on Photo-fluidity, Chalcogenide Whispering Gallery Mode Cavities (OMEGA) proposes the elaboration of an optical memristive component, fusing together the exotic photo-sensitivity properties of chalcogenide glasses (ChGs) and the extreme power accumulation and modal state density of whispering gallery modes (WGMs) resonation inside spheroid microcavities.
A highly competitive, post-doctoral research fellow is sought for the project OMEGA, for 12 months initial contract, with an additional up to 12 months, extension foreseen upon performance. The successful candidate must have a PhD degree in Physics or Electrical/Electronic Engineering, with a strong experimental/theoretical background in Optical Fiber Devices and/or Whispering Gallery Mode systems, being proven by publications record, previous experience and/or thesis subject and reference letters. The applicants must provide at least two names (preferably three) of academics who can provide reference letters. Previous background on Glass science/photosensitivity will be considered as a strong asset. Applications without satisfying the above criteria will not being considered.
FORTH is a major research organization in Greece, with the mission to pursue high quality basic and applied research. IESL focuses its research activities in the fields of lasers and applications, materials science, microelectronics and devices and theoretical-computational physics, being the main laser research centre in Greece. The Laser and Applications Division at FORTH/IESL has a strong international presence with diverse activities: atomic/chemical physics, pump-probe studies, and nano-processing, photonics and fibre optics, biomedical applications of lasers. FORTH/IESL is a leading research institute in Europe, participating in hundreds of EU funded projects, also operating as a European Research Infrastructure (Ultraviolet Laser Facility-ULF) for more than 25 years, and is currently supported through the Access to Research Infrastructures Activity of the Human Research Potential Programme of the EC. FORTH-IESL is also a member of the Extreme Light Infrastructure, ACTPHAST 4R & 4.0, the Joint Undertaking ENIAC, the NFFA-EUROPE, IPERION-CH/MOLAB, and ESMI facilities.
The successful applicant will work at the Photonic Materials and Devices Laboratory (PMDL) of FORTH/IESL (https://pmdl.iesl.forth.gr/), with a research agenda focused in the research of materials, designs and laser based fabrication methods for the development of Photonic Devices mainly in fibre geometry, with emphasis given on photonic crystal fibres, whispering gallery modes and new types of optical fiber sensors. PMDL provides a rich photonic infrastructure and unique device development know-how, while operating in a multi-cultural/national mode and providing access to international collaborations. The successful applicant will be based at the premises of IESL, however, since the project OMEGA is a collaborative scheme between FORTH/IESL and FORTH/ICE-HT, short visits to the premises of ICE-HT (Patras) for work on material science issues with Dr. Spyros Yannopoulos are anticipated.

Schlumberger is an oilfield services company employing approximately 100,000 people representing over 140 nationalities and working in more than 85 countries. The company commitment to technology and quality is a basis of its competitive advantage, hence we have a strong ethos of technical excellence. The company thus strives to be at the forefront in key research and engineering technologies.
Schlumberger Cambridge Research is the company’s centre of excellence for “well construction”. This encompasses work on a range of processes including research on the details of flow of a wide range of complex fluids. These processes are ubiquitous within the industry and are critical to Schlumberger’s business. Whereas the company uses a number of in-house simulators to model and design the well-construction process, there are many unknowns, and many opportunities to improve both the efficiency and the safety of these processes.
In this seminar I will introduce the company, describe some particular challenges and then describe recent detailed rheological investigations of drilling fluids.
