Optical Nanoantennas for Ultrafast Nonlinear Spectroscopy of Individual Nanosystems
… quantisierter Zustände eines einzelnen CdSe Nanodrahtes. Wir messen das anregungsinduzierte Bleichen unterschiedlicher Exzitonenübergänge und erhalten Einsicht in zuvor versteckte Prozesse und Größen wie zum Beispiel die zeitabhängige Population verschiedener Zustände. Die beobachteten …

Dielectrophoretic formation of nanowires and devices
We report the self assembly of nanostructures via. the bottom-up approach by dielectrophoresis. Dielectrophoresis deals with the force on an electric dipole placed in an external in-homogenous field. The force depends on the geometry and volume of the dielectric material and on the frequency and …

Ab initio Beschreibung der elektronischen Struktur und der Transporteigenschaften von metallischen Nanodrähten
Ab initio calculations of the electronic structure of freestanding Cu and Na nanowires with a diameter of few atoms are presented. The calculations are based on density functional theory in local density approximation using a Screened Korringa-Kohn-Rostoker-Green's function method. The method was …

Shape Evolution of Nanostructures by Thermal and Ion Beam Processing
Single-crystalline nanostructures often exhibit gradients of surface (and/or interface) curvature that emerge from fabrication and growth processes or from thermal fluctuations. Thus, the system-inherent capillary force can initiate morphological transformations during further processing steps or …

Integrated nanoscaled detectors of biochemical species
Rapid and reliable diagnostics of a disease represents one of the main focuses of today’s academic and industrial research in the development of new sensor prototypes and improvement of existing technologies. With respect to demographic changes and inhomogeneous distribution of the clinical …
