This study addresses a critical measurement error in assessing the mechanical properties of perovskite nanoparticles by replacing sharp atomic force microscope probes with blunt ones to prevent sample destruction. By integrating 3D modeling that accounts for particle irregularities and probe geometry, researchers now obtain accurate data on durability essential for developing flexible electronics like folding screens and solar cells. The findings provide a more reliable framework for characterizing these fragile semiconductor compounds before they are deployed in commercial devices.
ITMO team uses a blunt probe to test perovskite nanoparticle strength

ITMO University physicists devised a new method to assess the durability of perovskite nanoparticles, crucial for flexible electronics.
Credit: Dmitry Grigoryev / ITMO NEWS · news.itmo.ru ITMO University physicists are refining durability testing for perovskite nanoparticles, key components in emerging flexible electronics, by swapping the standard atomic force microscope’s sharp needle for a blunt probe functioning as a miniature press. This novel approach avoids damaging the fragile semiconductor compounds, defined by the general formula ABX₃, which are currently being investigated for use in devices like folding screens and solar cells. To further refine accuracy, the team…
