A03 – Control of vibrational modes and dissipation of nanomechanical resonators

Funding period: 2008 – 2015

Principal investigators: Elke Scheer, Thomas Dekorsy, Paul Leiderer

Scientific staff: Elaine Barretto, Artur Erbe (consultant), Martin Großmann, Chuan He, Nico Krauß, Oliver Ristow, Fan Yang, Reimar Waitz

By optical profilometry we study the dispersion relations of silicon membranes in the thickness range of several ten to 10 nanometers. We asses a frequency range of up to 12 MHz and tune the frequency by laterally patterning the membranes. We will study the higher excited modes of doubly-clamped siliconnitride cantilevers for frequencies up to 10 GHz by asynchronous optical sampling (ASOPS, see project A01). We will use electrical characterization in the range of several MHz up to several GHz for studying the groundmodes. In addition we will study diamond membranes (with very high eigenfrequencies) and nanoresonators made of shape-memory alloys, the latter ones because their eigenfrequencies can be switched by temperature. We will use focused ion beam patterning for tuning the mode spectrum of the membranes and other nanoresonators.
