This thesis explores the possibility of using advanced device geometries and heterostructure engineering to manipulate, control, and study the electrical and optical properties of semiconductor nanowires. The first part of the thesis investigates the use of different gate-all-around architectures for creating new types of gate-controlled nanowire devices, primarily intended for fundamental studies
In recent years, contact-induced language changes have been hotly discussed (e.g. Heine 2003; Heine and Kuteva 2005), and in this paper, a similar line of argument is presented concerning the Slavic languages, and a similar developmental path is applied to minority languages. Based on analogy, future state of minority languages is predicted. Some languages in the Indo-European family are known to

Optical spectroscopy, and in particular laser spectroscopy, provides numerous possibilities for advanced diagnostics and multi-spectral imaging with real-time capability. We describe applications to the environmental and medical fields and it is noted that the basic approaches are very similar in both areas. Environmental diagnostics discussed includes satellite imagery, long-path absorption atmos
The all spectrum absorption efficiency appears in the physical bounds on antennas expressed in the polarizability dyadics. Here, it is shown that this generalized absorption efficiency is close to $1/2$ for small idealized dipole antennas and for antennas with a dominant resonance in their absorption. Also, the usefulness of this parameter is analyzed for estimation of antenna performance. The res
Analog circuits are often specified using non-linear equations, which are difficult to analyze. Therefore, test generation and diagnosis are problematic issues in practice. In this paper we propose a new method for diagnosis of analog circuits that uses combined information from tests at different frequencies. By solving simultaneously the resulting equations (one for each test frequency), we get
