摘要: A new approach of periodic production dusty plasma consisting pulsed injection hexamethyldisiloxane (HMDSO) in argon axially asymmetric radiofrequency (RF) discharge was investigated this work. The range operating conditions which can exist closely examined. obtained results clearly show that a net periodicity the formation/disappearance dust particles be maintained on very large scale duration. significance axial asymmetry to behaviour is revealed by development an shape void shifted towards powered RF electrode. key role reactive gas and its each stage oscillating process disclosed optical electrical measurements. It shown period inversely related HMDSO time. Moreover, impact time over short (5 s) indicates conflicting played reduction during reappearance off. electronegative behavior presence negatively charged seems explain energetic modifications discharge. frequency analysis floating potential reveals all these cyclic processes. Particularly, 10–200 Hz range, evolution one generation observed.
