Mixing thin Sn films into polyetheretherketone (PEEK) substrates using Sn+ ion beams can turn this inherently insulating polymer metallic. Control of this process changes the sample's conductivity by over ten orders of magnitude (see picture). This can be used to produce high-performance, robust, low-cost thermometers, which can be easily tailored to the desired temperature range.
