This work investigates the photoinduced interactions between different organic chromophores, thus identifying possible materials for organic photovoltaic applications. The intermolecular electron transfer (ET) in layered ...

It is foreseen that nanoimprint lithography, NIL in short, will in the course of time have a strong impact on device applications which require precise and affordable nano-scale surface fabrication. My Thesis investigates ...

In this thesis we are working with a function theory on the hyperbolic upper-half space. The function theory is called the hyperbolic function theory and it is studied since 1990's by Heinz Leutwiler and Sirkka-Liisa ...

Optically-pumped semiconductor disk lasers are light sources that combine traditional solid state disk laser architecture with gain material made of semiconductor nano-layers. The laser design offers an attractive oppportunity ...

This thesis investigates novel dispersion compensation methods for mode-locked fiber lasers and the dynamical properties of ytterbium and thulium-holmium gain materials. The emphasis is on dielectric thin film structures ...

Photoinduced electron transfer of several dyads and triads consisting of porphyrins or phthalocyanines as electron donors and fullerene as acceptor was studied. Efficient electron transfer was observed in the studied ...

Water services systems are essential to public health, economic development and the state of the environment. In order to secure the quality of services as well as ensure reasonable customer charges and sufficient investment, ...

Ultrafast fiber lasers with superb pulse and beam quality are becoming important in various fields of applications including high-precision material processing, bio-medicine, fiber optical communications, and ranging. This ...

In this Thesis, technologically important III-V semiconductors are studied. Structural and electronic properties of bismuth (Bi) stabilized InP(100) and GaAsN(100) are explored. Atomic models for the Bi-stabilized surfaces ...

Rapid advances in electronics integration, miniaturisation and processing power have brought about a noticeable increase in computing and electronic devices that now surround us in our daily lives. We use computers and ...
