Fabrication process. (a) Sketch of the vacuum apparatus for growing nanofibres. The Knudsen cell with the p6P molecules is situated on the right side; the cooled sample holder with mica discs and masks is on the left side. The quartz microbalance is sitting to the right from the sample holder. Above and below the sample holder are the infrared heating bulbs with heat shields. (b) Deposition process timeline for the growth of p6P nanofibres that constitute a nanotag. Red dots, temperature of the p6P oven; black squares, temperature of the mica substrate; blue triangles, nominal p6P film thickness.
