Getting connected

In the last two weeks, thanks to an early part secondment, I had the opportunity to get to know many different preparation and exfoliation possibilities at CIC nanoGUNE. Besides the many scientific experiences, I came into contact with many friendly and helpful scientists and was able to enjoy the time there, also because of the good weather. Besides Marco, who works with me in Zurich, I also got to know two other ESRs personally here, Mayank and Eoin. Fortunately, my time in San Sebastián/Donostia coincided exactly with a statistically significant accumulation of birthdays, so I got to enjoy freshly baked cake at work surprisingly often.

I spent most of my time at the glove box exfoliating various non-stable materials and building stacks with the stamping system. In the picture you can see the transfer process, where the flakes are transferred to a substrate using polydimethylsiloxane (PDMS). With this technique, precisely aligned complex hetero structures can be produced successively.

Back in Zurich, I will continue the exfoliation of van-der-Waals crystals of different materials. The new knowledge I gained at CIC nanoGUNE and especially the personal tips on the exfoliation for specific materials will help me to fabricate different types of samples in the near future, either in a controlled environment or under ambient conditions.

Finally, I can only thank you for the wonderful time and send my greetings to Spain.
