Organic and carbon nanotube electronics for flexible nanoscale high-frequency circuits and physical unclonable function

Thin films of carbonaceous materials, such as organic semiconductors and carbon nanotubes, continue to show promise for various novel electronics applications, especially where flexibility and large-area processing are important factors. In particular, exciting progress has recently been made in the development of flexible nanoscale high-frequency organic transistors and circuits. In addition, new application spaces continue to emerge for carbon electronics. Here, a burgeoning opportunity in the field of physical unclonable function (PUF) is discussed, with multi-contact field-effect transistors based on random networks of unsorted single-walled carbon nanotubes (SWCNTs) as a potential platform for scalable electronic PUFs.
