Nanoscale Cleaning
A clean surface with controlled and tunable surface chemistry can be critical for improving interfacial, biological, and electronic properties of materials for optimal device and structural performance. Plasma surface treatment removes nanoscale organic contamination and alters surface chemistry without affecting the bulk material. This page provides brief summaries on the benefits and applications of plasma cleaning.
