The electronic behavior of thin films is heavily influenced by the contact with their surroundings, as exemplified by the recent discovery of 2D superconductivity at a thin film interface. However, information about how such entwined states come into existence is limited by the lack of tools capable of visualizing such buried interfaces.

Scientists at Dongguk University have found a way to create printed p-channel thin-film transistors by using the abundantly available and environmentally-friendly copper(I) iodide semiconductor at room temperature. Their energy-efficient and cost-effective fabrication method for these transistors may pave the way for developing low-cost and novel optoelectronic devices.
