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, photodetectors, LEDs). 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 insight as well as for industrial applications. This conference 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.
- Solution-based bottom-up synthesis of 2D nanomaterials (colloidal methods, exfoliation, metal-organic approaches)
- Physical properties of solution-based 2D nanomaterials (spectroscopy, thermoelectrics, mechanical and electronic properties, electron and spin transport)
- Chemical properties of solution-based 2D nanomaterials (chemical stability, chemical self-organization, photocatalytic activity)
- Self-organization of 2D nanomaterials into superstructures
- Devices based on solution-processed 2D nanomaterials (tranistors, solar cells)
- Theory of 2D materials (DOS, optical properties, growth mechanisms)

Vanmaekelbergh's research started in the field of semiconductor electrochemistry in the 1980s; this later evolved into the electrochemical fabrication of macroporous semiconductors as the strongest light scatterers for visible light, and the study of electron transport in disordered (particulate) semiconductors. In the last decade, Vanmaekelbergh's interest shifted to the field of nanoscience: the synthesis of colloidal semiconductor quantum dots and self-assembled quantum-dot solids, the study of their opto-electronic properties with optical spectroscopy and UHV cryogenic Scanning Tunneling Microscopy and Spectroscopy, and electron transport in electrochemically-gated quantum-dot solids. Scanning tunnelling spectroscopy is also used to study the electronic states in graphene quantum dots. More recently, the focus of the research has shifted to 2-D nano structured semiconductors, e.g. honeycomb semiconductors with Dirac-type electronic bands.
