An exciting approach to generating these plasmas is the use of piezoelectric transformers. These devices use mechanical resonance to generate high voltages in a compact form, thereby igniting an atmospheric cold plasma. One challenge here is introducing precursors into the plasma to deposit homogeneous functional layers without damaging the piezoceramic due to thermal stress or layer residues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The work is related to this research project:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The work is part of an industrial project with a manufacturer of PECVD coating systems. The goal is to simplify the coating process by eliminating the need for complex high-frequency and low-pressure technology. The integration of piezoelectric elements promises to significantly simplify the process and increase efficiency for the local coating of surfaces.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Objective:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The objective of this work is the experimental commissioning and characterization of a piezoelectric plasma source for PECVD deposition. The aim is to investigate how process parameters (e.g. gas flow, electrical control of the piezoelectric element, gas mixture) affect the plasma parameters and the resulting coating quality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Your task:<\/h3>\n\n\n<style type=\"text\/css\">#table-from-csv-block_c708b991fb43a9857781f1eb45ec2634 table:not(thead) td:before { content: attr(data-col-name);
