The investigation of hydrogen in Atom Probe Tomography remains a relevant challenge. Its low mass, high diffusion coefficient, and presence as a residual gas in vacuum chambers generate multiple complications for APT investigations. Different solutions were proposed in the literature to charge our sample, such as ex-situ charging coupled with cryotransfer [1], or hydrogen charging at high...
APT analysis of polymers has been relatively limited compared to many other material systems due to sample preparation, data collection and data analysis challenges. Polymers are often beam sensitive and Focused Ion Beam (FIB) sample preparation is often avoided, leading to approaches based on spray deposition of polymer films [1] or self assembling monolayers [2] onto pre-fabricated...
