Growth origin of large-scale fiberform nanostructures in He–W co-deposition environment

LFN growth on meshes

LFN formation

Figure 3a–d shows images representing the formation process of LFNs on the W-plate, which were captured by an optical camera. LFNs were grown from the left edge of the sample, which is close to the sputtering source, and grew toward the lower right direction, which is consistent with the plasma flow³³. Figure 3e–h shows pictures representing the formation process of LFNs on the \(\sharp 50\) W mesh. After He–W co-deposition, LFNs were formed on the W plate and all kinds of W meshes; the most different results from the W plate were observed on the
