A Graphene Nanoribbon Memory Cell



original image

A graphene nanoribbon memory cell is fabricated by patterning graphene into nanoribbons using V2O5 nanofibers as etching masks. A pronounced memory effect is observed under ambient conditions. Reliable switching between two conductivity states is demonstrated for clock frequencies of up to 1 kHz and pulse durations as short as 500 ns for > 107 cycles.
