PAPER transistors could end the hunt for alternatives to silicon chips and herald the introduction of electronic devices cheap and bendy enough to use on disposable food cans.
“Paper transistors were tested for two months without any deterioration”
The transistors are the work of Elvira Fortunato of the New University of Lisbon in Portugal and colleagues, and were reported in this month’s IEEE Electron Device Letters. Fortunato and her team built the transistors by coating both sides of a sheet of ordinary paper with metal oxides. They then applied aluminium contacts onto the coated paper.
The paper acts both…
