Quantum confinement in semiconducor nanomaterials offer a flexible material platform that has great promise for engineering functional solids, solutions, composites, etc. for a wide range of opto-electronic applications. The synthesis, investigation, and utilization of these novel nanostructures lie at the interface between chemistry, physics, materials science and engineering. Learning to control the opto-electronic as well as reactivity of the QD systems involves novel synthesis of structures, heterostructures, shapes, and aggolmerates and/or solids. Understanding electron dynamics, electron-phonon coupling, ligand-QD electronic interactions, surface defects, QD-QD coupling, light-in/light-out and other photophysical and physicochemical properties will yield the necessary design principles for the incorporation and development of QD systems and devices. The NGFM20 symposium will bring together leading scientist to discuss these exciting research avenues and directions.

Solution-processable two-dimensional nanomaterials (nanosheets) are attracting increasing research efforts due to their extraordinary electronic, phononic, optical and mechanical properties, which makes them promising materials for a myriad of applications (spintronic devices, field-effect transistors, nanoscale sensors, batteries, inexpensive photodetectors,
LEDs, and lasers). 2D materials can be obtained by exfoliation of bulk materials or grown on substrates by MBE or CVD. However, these methods are not suitable to produce large amounts of free-standing 2D nanosheets and lack control over their shape and lateral dimensions. Solution-based "bottom-up" colloidal chemical methods offer an appealing alternative, and are emerging as promising routes for fundamental insights as well as for industrial applications. This symposium intends to bring together the multidisciplinary scientific community working on this nascent field, and will address not only the bottom-up solution synthesis of 2D nanomaterials, but also their chemistry, physics and applications in devices.

- Self-organization of 2D nanomaterials into superstructures
- Devices based on solution-processed 2D nanomaterials (transistors, photodetectors, solar cells, LEDs, lasers)
- Theory of 2D materials (DOS, optical properties, growth mechanisms)

Nanocrystals have reached a mass market with their use as light sources in displays. While this first application relies on wide band gap materials, narrower band gap materials with optical properties in the infrared appear equally promising for the emergence of low cost optoelectronic devices, and because the infrared is mostly out of the reach of organic materials. Potential applications include solar cell and infrared light sensing.
The session will be dedicated to all aspects relative to infrared active colloidal nanocrystals from material synthesis up to the device application. Lead chalcogenides (PbS and PbSe) have been the most investigated narrow band gap nanocrystals and present a high level of maturity for synthesis control and transport properties. Other materials have also raised interests such as mercury chalcogenides to reach longer wavelength, and less toxic compounds such as doped oxide.
The session will also focus on the material properties of these infrared nanocrystals. This include the nature of their optical transitions which can present interband, intraband or plasmonic absorption and their transport properties. Finally, a last aspect of the discussion will be focused on the device integration of these nanocrystals for various applications such as light sensing, gas sensing, smart windows

The emergence of halide perovskites has taken the semiconductor community by storm leading to a plethora of applications utilizing these amazing materials. As the field matures, a number of scientific questions appear, relating to the nature of the structural instabilities and the mechanisms of charge-transport in halide perovskites. Debates relating to the nature of chemical bonding or the contribution of the phonons to the optoelectronic properties are heating up and answering these questions requires a multidisciplinary effort. Key questions asking whether the superb semiconducting properties of the lead-based APbX3 perovskites are limited to the lead metal alone or whether there are other – preferably less toxic – metal halide-based materials with similar optoelectronic properties. The scope of the symposium is to cover the latest discoveries in these directions, but it also provides an open forum for discussing alternative classes of non-perovskitic halide-based materials and unconventional theoretical concepts. The present symposium has the ambition of blending together researchers working on materials design, from synthesis to crystal growth, spectroscopy and theory.
