Electrical tuning of dc bias induced acoustic resonances in paraelectric thin films

Alexander Tagantsev, Nava Setter, Andreas Nöth

A theoretical model for the dc bias dependence of induced acoustic resonances in paraelectric materials is presented. The field dependent piezoelectric constitutive equations were derived from the Landau free energy expansion with respect to the ferroelect ...

Electronic properties of carbon nanotubes : combined effect of geometry and correlations

Thomas Gloor

In this thesis we study the interplay between electronic correlations and geometry in single-walled carbon nanotubes by microscopic model calculations. Electronic correlations are expected to be strong because of the low dimensionality of carbon nanotubes. ...
