Viscoelastic properties and efficient acoustic damping in confined polymer nano-layers at GHz frequencies.

Scientific reports

Hettich M, Jacob K, Ristow O, Schubert M, Bruchhausen A, Gusev V, Dekorsy T.
PMID: 27633351
Sci Rep. 2016 Sep 16;6:33471. doi: 10.1038/srep33471.

We investigate the viscoelastic properties of confined molecular nano-layers by time resolved optical pump-probe measurements. Access to the elastic properties is provided by the damping time of acoustic eigenmodes of thin metal films deposited on the molecular nano-layers which...
