Graphene, one layer of carbon atoms, is the first real 2D material. It combines many amazing properties into one material and has a high potential in both basic sciences and applications. It has high mobility, high thermal and electrical conductivity, high flexibility, high optical transmittance, etc. It is predicted to be the most promising next generation electronic materials. Today, cellphones with graphene screen, Li batteries with graphene electrodes, and other graphene products are already in the market. Currently, Chalmers is leading the EU Graphene Flagship, which is the largest ever project in EU history. Therefore, Chalmers offers an idea work place for researching graphene.
For any type of applications, the first step is material synthesis. Typical graphene synthesis technologies including micromechanical exfoliation using sticky tapes, liquid phase exfoliation, graphene oxide reduction, SiC decomposition, and chemical vapor deposition (CVD). Clearly, CVD is the most compatible with existing semiconductor technology and has the highest potential in high-end electronic applications. In Chalmers we have several CVD systems for graphene deposition, each with its own characteristics. This project deals with the production of large area graphene on metallic substrate such as Cu. We will grow graphene by CVD on these metal foils and transfer them to insulators (SiO2) for further characterization. Our target is to boost the material quality in terms of high mobility, good Raman signal, and low sheet resistance. If successful, we will further explore the related electronic applications in functional devices.
During this project, you have the chance to work in the world-class clean room and have access to the world’s most advanced CVD system for graphene. After the project you will become an expert in graphene growth and transfer, as well as typical characterization methods. You will obtain knowledge of graphene physics. It is a good starting point for further career advancement.
The master project belongs to Quantum Device Physics Laboratory of Department of Microtechnology and Nanoscience. It lasts 1 year, but 0.5 year is also acceptable. You should ideally have a background in physics, chemistry, material, or electronics.
