(March 23, 2015) Its theoretical properties made graphene a »wonder material«
overnight: it is up to 200 times harder than steel, six times lighter, strong
but flexible, environmentally friendly and the world’s thinnest material.
Measuring only a single atom layer, about a one hundred-thousandth the diameter
of a human hair, it still retains a remarkable level of conductivity. At the
Fraunhofer Institute for Applied Solid State Physics IAF, these properties will
be put to practice: as a nearly massless electrode for piezoelectric
resonators, as used in bandpass filters of smartphones.
