Open-Air Cold Plasma Device Leads to Selective Tumor Cell Cytotoxicity [PDF]

Applied Sciences, 2021
The need for effective and safe therapies for cancer is growing as aging is modifying its epidemiology. Cold atmospheric plasma (CAP) has gained attention as a potential anti-tumor therapy. CAP is a gas with enough energy to ionize a significant fraction of its constituent particles, forming equal numbers of positive ions and electrons. Timely-resolved

Plasma induced damage on AlGaN/GaN heterostructure during gate opening for power devices

Journal of Vacuum Science & Technology A, 2023
During the fabrication of metal oxide semiconductor high electron mobility transistor based on AlGaN/GaN heterostructure, gate patterning is recognized as the most critical step that can lead to electrical degradation of the transistor. In this work, we performed the SiN cap layer plasma etching processes by two fluorine-based plasma processes (SF6/Ar ...
