Description
Thin film samples can be highly influenced by interfacial properties and often have strongly depth-dependent properties. This effect can be even stronger in materials or materials produced by additive manufacturing, where the material is deposited sequentially in layers. While studying film-averaged and near-surface measurements can be straightforward, depth-dependent measurements remain a challenge, but are crucial. In this work, we found that with specific conditions, we can remove thin layers of stable polystyrene glass from a film with only a small effect on the remaining material and its stability by a dissolution process. This suggests that the dissolution process in this case is highly localized and introduces a promising candidate for learning about depth-dependent properties of stable polystyrene glasses produced by vapour deposition.
