ATUMS combines research diversity and possibilities to one joint goal
Silicon attracts much interest throughout a diversity of different research fields, as it is a widely used material in our everyday life and the material that enables modern information technology. For the near future, smaller, faster and stable material and cheap incorporation within electronics are just a few goals, which need to be achieved.1,2,3 In this context the new properties of nanostructured materials, which exhibit outstanding and size dependent properties due to quantum confinement effects, are of big importance.4,5
In this project, we research the use of highly sensitive two-dimensional silicon nanosheets (SiNS) in ambient conditions. The interesting optoelectronic properties of this nanomaterial open new possibilities for fast responsive and therefore highly sensitive electronics. Especially its functionalization and the synthesis of SiNS based composites enable the application in ambient conditions and promise a facile fabrication of long living devices. New synthesis routes for covalent surface modification could already be established by our team. Hereby not only radical induced functionalization of SiNSs was performed,6 but also a one-step synthesis of covalent polymeric nanocomposites.7
