Happy new year everyone ! The SPM Lab wishes you great successes in your future work and life. To start off the new year well, you can read our new paper entitled Co-evaporation of CH3NH3PbI3: How Growth Conditions Impact Phase Purity, Photostriction, and Intrinsic Stability, out in ACS Applied Materials and Interfaces. Congratulations to everyone involveld. You can access it via:
Besides, our XPS setup has now been installed in our UHV SPM and can now be used. Looking forward for the UPS extension !
