Helium plasma irradiation to various metals leads to peculiar morphology changes as
forming fiberform nanostructures called fuzz when a certain set of conditions is satisfied. In …

Helium (He) plasma treatment can be a versatile tool to fabricate nanostructures on a
surface and change the surface chemistry. Herein, vanadium (V) thin film is exposed to …

Low-energy helium (He) plasma irradiations were conducted on ruthenium (Ru) and
rhenium (Re), which have hexagonal close packed (HCP) crystal structures. Growth of linear …

Characteristic fibrous nanostructure, known as fuzz, is formed by a helium plasma exposure
of metal surfaces at certain temperatures. Applications of He-induced nanostructure to …

A fiberform nanostructure was synthesized by exposing high-density helium plasma to a 100
nm thick tungsten thin film in the linear plasma device NAGDIS-II. After helium plasma …

Tungsten thin films were deposited onto silicon substrates using sputtering techniques, and
helium plasma irradiation was performed in a linear plasma device. Observations of the …

We performed helium (He) plasma irradiation to molybdenum (Mo) substrate with auxiliary
Mo deposition. Different from W cases, large-scale fiberform nanostructure (LFN) growth did …

Large-scale fiberform nanostructures (LFN) are formed on the tungsten (W) surface with He-
W codeposition environments. In this study, we conducted annealing experiments at 1473 …

Morphology changes by helium plasma irradiation are investigated on four metals that have
hexagonal close packing crystal structures. Straight fiberform nanostructures (FNs) were …
