Abstract
  • Many types of materials make up the world, and one subset of these materials are colloquially called 2D. This dissertation encompasses a range of very thin materials and looks for ways to study their properties. First, a functionalization method for MoS2 is presented. By using chemical vapor deposition, MoS2 is able to be functionalized with various organic monolayers that do not harm the underlying electronic properties. Next, a study is presented on how new derivatives of TES-ADT can be used in OFETs. By working on improving the film quality, the electronic properties of these materials can be improved. Lastly, a different method for the preparation of 2D mixed perovskites is presented. Using the melt infiltration approach, different layer numbers of mixed perovskites can be prepared. This approach gives a way to look at and study the formation of mixed perovskites over time.
