1/9 Sometimes you've projects you enjoy and you have a lot of fun. When they work... It's awesome!!!

Well, in the last year we've learnt how to make the thinnest possible ommelettes and we ended up using them to fabricate field-effect transistors 🤯

Our work "Combining Freestanding Ferroelectric Perovskite Oxides with Two-Dimensional Semiconductors for High Performance Transistors" is published online (#openaccess). I prepared a thread to briefly explain what we did 👇 pubs.acs.org/doi/10.1021/ac… In the last 12 years the sci-community has learn a lot about techniques and tools to handle freestanding atomically thin layers thanks to the isolation of 2D van der Waals materials: doi.org/10.1039/C7CS00…

With the COVID-19 situation scalating so fast our lab @icmmcsic has been closed down for almost 3 weeks now. #StayHomeStaySafe

I've been thinking about interesting experiments that can be carried out at home with basically no measurement tools at all.👇Thread in! Sometime ago I wrote a little paper about a method to characterize the mechanical properties of micro-fibers (like carbon fibers):
