| contents | This study reports a low-frequency alternating current (AC) power supply as a novel approach for generating low-pressure capacitively coupled Ar-O2 plasma, offering advantages in cost, compactness, and operational simplicity, which are crucial for both material science and biological applications. The effectiveness of low-frequency AC-generated plasma against traditional RF systems by examining key plasma parameters such as electron density, electron temperature, and electron energy distribution function (EEDF), are investigated. Experimental results revealed that AC power supply could effectively produce low pressure Ar-O2 plasma with comparable properties to RF systems. Most notably, the AC-generated plasma achieved a significant reduction in bacterial growth, suggesting its potential as a more economical and flexible alternative for enhancing plasma-assisted applications in sterilization and material processing. |
