NEMS NEMS (Nanoelectromechanical System) is used to describe devices integrating electrical and mechanical functionality on the nanoscale. Projects 1. Nonoswitch
Compared
with field transistor, nano-switch has sharper
switching characteristics. This may help reduce power consumption.
Graphene is
a two-dimensional honeycomb-arranged crystal of carbon atoms, which has
very
unique electrical and mechanical properties. Currently graphene is
considered
to be an excellent material for NEMS. We used a novel way to transfer
patterned
graphene flakes onto desired substrate and fabricated free-standing
graphene
arrays. The top graphene film could be pulled into electrical contact
with the
low resistive silicon substrate by applying DC voltage between them.
Contact was broken by elastic forces after
bias was removed.
