La interacció de la llum amb els òxids metàl.lics (MOX's) semiconductors, sempre i quan l'energia dels fotons sigui superior a l'amplada de la banda prohibida, produeix un increment significatiu de la densitat de portadors ...
The present thesis is included in the field of nanobioelectricity. That is, understanding the electrical properties of biological specimens at the nanoscale (< 200 nm). To do so we used an electrical variation of the ...
The assessment of the electrical properties of biomolecules at the nanoscale becomes necessary for gathering previous basic knowledge and for the control of the biosensor fabrication. I developed instrumentation, protocols, ...
In this thesis, pH and potassium all-solid-state ISE based on potentiometry and bioimpedance sensors were designed, fabricated and integrated in a miniaturized array for its application in endoscopic surgery for in vivo ...
In the Transmission Electron Microscope (TEM), an incident electron suffers both elastic and inelastic scattering by the solid state thin sample that is being characterised. In the event of inelastic scattering, the incident ...
The main topic of this thesis is the theoretical and computational investigation of the opto-electronic properties of large arrays of semiconductor quantum dots embedded in an insulator matrix. For that purpose, an electronic ...
Bona part dels processos naturals i de les activitats humanes impliquen processos de transferència d’energia, que en part, o en la seva totalitat es dissipen en el medi. L’aprofitament de l’energia residual present en ...
The significant development in medical diagnostics and imaging has brought up a lot of new wireless capsule endoscopes coming to health care market. The capsule has been able to minimize patient discomfort and pain during ...
The rationale for a telemedicine system is the use of Information and Communications Technology (ICT) for the remote transmission of biomedical data and the remote control of biomedical equipment, in order to improve the ...
L'espectroscòpia òptica dels ions Tm3+ i Yb3+ en tungstats dobles monoclínics és molt important per desenvolupar dispositius làser d'estat sòlid. Els tungstats dobles monoclínics són molt interessants pels avantatges que ...
En esta tesis doctoral se ha estudiado de forma sistemática la relación entre los campos eléctricos y las células, y los efectos que éstos tienen a diferentes niveles (supervivencia, metabolismo, expresión proteica, ...
Patterns are a collection of forming units predictably repeated over a defined magnitude. Researchers have used patterns to guarantee the functionality and repeatability of their study. For that, the obtained data is ...
The next generation of particle colliders will be characterized by linear lepton colliders, where the collisions between electrons and positrons will allow to study in great detail the new particle discovered at CERN in ...
The work developed during this PhD has embraced several topics that I divide in three blocks. Each block contains two chapters in this dissertation. Additionally, a general introduction of the different topics is provided ...
En esta tesis doctoral se estudia la problemática existente en la aplicación de los nanomateriales y la nanotecnología para la preparación de dispositivos basados en tecnología cerámica multicapa. Un punto clave de la ...
The context of this thesis is the design of CMOS low power RFIC's suitable for direct conversion architectures. Our starting point is the analysis of the characteristics of the integrated passive components (inductors and ...
Fuel cells are one of the promising technology at present to meet the growing demand of clean energy and technology. Among the different varieties of fuel cells, Solid Oxide Fuel Cell (SOFC) research is advancing towards ...
Silicon and silicon-germanium nanostructures were grown, integrated, optimized and characterized for their application in thermoelectric generation. Specifically two kinds of nanostructures were worked: silicon and ...
In the last decades, there has been a huge proliferation of portable devices. Among them, consumer electronics such as mobile phones, music players, e-books, etc. are greatly extended. In order to provide these ...
The goal of this dissertation is the study and characterisation of high dose Carbon (C) implantation processes into Silicon (Si) and related materials for the synthesis of Silicon Carbide (SiC). The attainment of ...
