About the research project:
One of the most exciting discoveries in modern science is that materials can behave in completely new ways when they are only a single atomic layer thick. These so-called 2D materials are at the heart of next-generation technologies—from flexible electronics (transistors, memories, batteries) to ultra-sensitive sensors (solar cells, DNA sequencing, coatings). But how can we study something so incredibly small? In this project, we will explore 2D materials using powerful techniques that scientists use in real research labs. We will prepare our own samples by mechanically exfoliating layered materials such as graphene and other atomically thin structures. By transferring these layers onto different substrates, we will create systems that can be further investigated. We will then use spectroscopic techniques, such as Raman and photoluminescence, to understand how these materials interact with light, thereby revealing key properties like the material’s chemical composition, number of atomic layers and the strength of interaction between them. Additionally, electron microscopy will be employed to visualize the samples and correlate the secondary electron contrast with their thickness and structure.
Together, we will prepare the samples, analyze real data, compare different measurement techniques, and uncover how the structure of a material at the atomic scale determines its behavior. By combining multiple approaches, we will build a complete picture—just like solving a scientific puzzle. At the end, you will have experienced how cutting-edge nanoscience research is performed and gained insight into a field that is shaping the future of technology.
