Sample interview questions: Have you ever worked with non-thermal plasmas? If so, can you provide examples?
Sample answer:
Yes, I have extensive experience working with non-thermal plasmas. Non-thermal plasmas are characterized by a high degree of ionization, while maintaining a relatively low temperature compared to the surrounding gas. This unique combination of properties makes non-thermal plasmas useful for a wide range of applications, particularly in materials processing and surface modification.
In my previous role as a Plasma Physicist at [Previous Institution], I was involved in several projects utilizing non-thermal plasmas. One notable project focused on developing a novel plasma-based surface treatment process to enhance the adhesion properties of polymer films. We used a radio frequency (RF) plasma discharge to generate a non-thermal plasma containing a mixture of argon and oxygen gases. The plasma was then directed onto the polymer surface, which resulted in the formation of reactive oxygen species (ROS) on the surface. These ROS promoted the formation of polar functional groups on the polymer surface, thereby improving its adhesion properties to various substrates.
Another project involved the use of n… Read full answer
