Sentence examples for nw tip from inspiring English sources

This can be explained by the widely accepted VLS/VSS growth mechanism that Ga precursors come from the diffusion and precipitation of Au-Ga alloy tips, and As precursors are mainly provided from the ambient vapor, because of the low solubility of As in Au[8, 20, 21], reacting with Ga at the NW tip and body interface to yield NWs.

The contact angle between the Ga droplet and solid NW tip decreases towards 90°, and the spreading of the droplet over the edges of the NW tip reduces as the NW diameter grows.

The NW tip morphology also changed with the NH4Cl concentration, from pyramidal to flat tips.

Each NW tip was fitted with a sphere.

The NW tip diameter and base diameter are too small to be distinguished when the growth duration is short.

In summary, a new experimental method to measure the friction between a NW tip and a substrate has been developed.

A novel polyimide fill-in and etch-back technique was employed to embed the NW tips into the membrane, such that the NWs were compressed and stretched by the membrane/proof-mass structure in response to the external vibrations.

Here we report the first experimental study on the friction between NW tips (ends) and a substrate.

Last, although our experimental method gave rise to the first measurement of the friction data between NW tips and a substrate, we are aware that it cannot measure the friction as a function of the progressively applied normal force.

For contacts between ZnO NW tips and a gold substrate, we found the adhesion force did not show noticeable change when the contact area was exposed to electron beam only for a short time (e.g., less than 10 s) [36].

For comparison, we also recorded neural signals using two tungsten electrodes without Au NW tips, implanted following an identical protocol and pair arrangement.
