To be more precise, they've made the first field effect transistors (FET) with a paper interstrate layer. The research team fabricated the devices on both sides of the paper sheet such that the paper acts simultaneously as the electric insulator and as the substrate. Furthermore, electric characterization of devices showed that the hybrid FETs' performance outpace those of amorphous silicon TFTs, and rival with the actual state of the art of oxide thin film transistors.
