Reduction of the temperature threshold for tungsten fuzz growth by helium pre-irradiation
Source abstract
Abstract
The formation of fuzzy nanostructures on tungsten by helium plasma irradiation has been widely reported in studies utilizing linear plasma devices, with results indicating that such structures only develop at temperatures exceeding 900 K. In this study, fuzz grows at ∼750 K in a two-step experiment: 1. substrate irradiated by helium plasma at a temperature over 900 K; 2. continue the irradiation at a temperature of ∼750 K. It is found that fuzz continues growing at ∼750 K after the pre-irradiation with a growth rate even higher than that at high temperatures, and the growth saturates after reaching a thickness ∼1800 nm. The possible mechanism is discussed using thermal desorption spectroscopy analysis.
