Characterization of Porous Silicon Nanoparticles for Biomedical Applications
(Turun yliopistoAnnales Universitatis Turkuensis A I 557, 2017-05-13)
Porous silicon (PSi) is an intriguing material for biomedical applications because a great variation of properties can be created by adjusting fabrication parameters.Physicochemical properties, including pore size, surface ...
Spectroscopic Studies of III-V Semiconductor Materials for Improved Devices
(Turun yliopistoAnnales Universitatis Turkuensis A I 505, 2015-01-17)
Defects in semiconductor crystals and at their interfaces usually impair the properties and the performance of devices. These defects include, for example, vacancies (i.e., missing crystal atoms), interstitials (i.e., extra ...
Properties of Galaxies and Groups: Nature Versus Nurture
(Turun yliopistoAnnales Universitatis Turkuensis A I 419, 2011-06-03)
Emission, kinetic and magnetic phenomena in rare-earth and transition metal doped ZnSe single crystals
(Turun yliopistoAnnales Universitatis Turkuensis A I 515, 2015-05-22)
In this work emission, optical, electrical and magnetic properties of the d- and f- elements doped zinc selenide crystals were investigated within a wide temperature range. Doping was performed in various technological ...
Studies on the Multifaceted Interaction of Atoms and an Electromagnetic Field
(Turun yliopistoAnnales Universitatis Turkuensis A I 415, 2010-11-27)
In this Thesis the interaction of an electromagnetic field and matter is studied from various aspects in the general framework of cold atoms. Our subjects cover a wide spectrum of phenomena ranging from semiclassical ...
Two-dimensional atom localization and Raman cooling of tripod-type atoms
(Turun yliopistoAnnales Universitatis Turkuensis A I 471, 2013-09-20)
Both atom localization and Raman cooling, considered in the thesis, reflect recent progress in the area of all-optical methods. We focus on twodimensional (2D) case, using a four-level tripod-type atomic scheme for atom ...
Radiation and matter interaction in strongmagnetic field of accreting neutron stars
(Turun yliopistoAnnales Universitatis Turkuensis A I 524, 2015-10-13)
Moment Operators of Observables in Quantum Mechanics, with Applications to Quantization and Homodyne Detection
(Turun yliopistoAnnales Universitatis Turkuensis AI 380, 2008-01-19)
The questions studied in this thesis are centered around the moment operators of a quantum observable, the latter being represented by a normalized positive operator measure. The moment operators of an observable are ...
Time-dependent Quantum Systems
(Turun yliopistoAnnales Universitatis Turkuensis A I 561, 2017-06-02)
This thesis discusses different aspects of time-dependent two-level quantum systems and their coherent dynamics. In the introductory chapters, we present some basic models used to study them and some basic results ...
Implementability of observables, channels and instruments in quantum theory of measurements
(Turun yliopisto, 2017-11-25)
Measurements play an integral part in any scientific theory. Indeed, the observations revealing causal behaviour and symmetries in our world of experience lie at the heart of determining the truth or the falsity of scientific ...
