High-Q Nanostring

Caption: Typical nanostrings made from electrospun masks on stressed silicon nitride film will not be perfectly parallel, but the process allows rapid, low-cost manufacture. The string in the foreground, 200 nm wide, 105 nm thick and 60 microns long, had the highest quality factor of any in the current experiment. Cornell researchers believe it is the highest Q achieved for strings this small operating at room temperature.
