This week I will finish my first secondment at ETH Zurich, where I learned some new processing techniques for device fabrication as well as analysis of data, especially the two band model to find the carrier density and mobility of both electrons and holes in the coupled quantum wells. I got a lot of insight into different topics and had fruitful discussions with the group members. ETH provides a great platform for high quality research. I had a really good experience there, even got some time to explore Switzerland and I would
like to thank QuESTech for this opportunity.
