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.
- Advanced solution-based bottom-up synthesis of 2D nanomaterials (colloidal methods, exfoliation, metal-organic approaches)
- Physical properties of solution-based 2D nanomaterials (spectroscopy, mechanical and electronic properties, electron and spin transport)
- Chemical properties of solution-based 2D nanomaterials (chemical stability, chemical self-organization, photocatalytic activity, interaction of organic and inorganic materials)
- 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)
