Plasma treatment removes nanoscale contamination and alters surface chemistry without affecting the bulk material properties. Depending on the process gases and process conditions used, plasma treatment can be used for cleaning, surface activation, and surface chemistry modification. Plasma can be applied to a wide variety of materials including heat sensitive ones and those displaying complex surface geometries.
Langmuir-Blodgett and Langmuir-Schaeffer techniques
Langmuir-Blodgett troughs are used for Langmuir-Blodgett or Langmuir-Schaefer deposition. Langmuir-Blodgett troughs include a set of barriers, a Langmuir-Blodgett trough top, a surface pressure sensor and a dipping mechanism as standard. The dipping mechanism holds the solid substrate and enables controlled deposition cycle(s). For Langmuir-Schaefer deposition, the Langmuir-Blodgett trough top is not always necessary and can in some cases be replaced by a Langmuir trough top.
