• was 15 µm in length and 3 µm in radius. The initial gap was 3 µm, and the pull-in voltage was over 21 V. In another publication [41], the authors used in the situ technique to glue Ge nanowires to electrochemically etched gold tips to form NEM switches. The pull-in voltage was 40–45 V with an initial

We focus on the elastically backscattered signal measured through a photomultiplier tube (PMT) with an aSNOM setup in conjunction with gold tips that were used as local probes. To remove the periodic background far-field

The fact that a strong enhancement is observed indicates that the resonance of the capacitive gap mode between the tip and the surface is close to the laser excitation wavelength. The measurements were

To obtain a tip with a radius down to 10 nm and low surface roughness, the gold tips were fabricated by electrochemical etching. A 100 µm
