Abstract:

Les technologies de films minces sur isolant apparaissent comme des solutions fiables pour la nano électronique. Elles permettent de dépasser les limites des technologies sur substrat silicium massif, en autorisant de faibles tensions d’utilisation et un gain en énergie significatif. En effet, les transistors à semi-conducteurs à grille métallique (MOSFET) avec un substrat totalement déplété (FDSOI) conduisent à des courants de fuites faible et améliorent la variabilité ce qui permet de diminuer les tensions d’alimentation en particulier pour les applications SRAM. A partir du nœud 14 nm, les

Abstract:

Dans le domaine photovoltaïque, les performances des cellules solaires sont impactées par deux problématiques majeures : les pertes par réflexion et les pertes par recombinaisons. Le premier objectif de ce travail est de diminuer la réflexion de la lumière à la surface du silicium en utilisant une couche antireflet de nitrure de silicium. Cette dernière est réalisée par pulvérisation cathodique magnétron en utilisant des gaz non toxiques (Ar, N2). Le deuxième objectif de cette étude est la passivation des centres de recombinaison au niveau de l'interface couche antireflet/silicium. Pour cela,

Abstract:

The main object of this thesis is the diagnostics of the diaphragm discharge generated in water solutions containing supporting electrolytes (mostly NaCl), and description of particular processes before and after discharge breakdown by DC non-pulsed voltage up to 2 kV. Although many applications of electric discharge in liquids have been developed during the last years, the exact mechanism of the discharge ignition is not sufficiently known up to now. Based on this reason, this work is focused on the investigation of processes before the discharge ignition, breakdown parameters and the dischar

Abstract:

This thesis concerns monitoring in Middle- and Low-Voltage distribution systems penetrated by distributed generation. Monitoring itself means measuring voltages and power flows and sending relevant data to the supervisory system. The first part of the thesis describes distribution systems with differences between individual voltage levels. The following chapter is focused on consequences of high share of renewable energy sources in distribution systems. Most of the problems are partially resolved by technical conditions for connection of the new power sources. However, difficulties with voltag

Abstract:

Current leakage in GaN thin films limits reliable device fabrication. A variety of Ga and N rich MBE GaN thin films grown by Rf, NH3, and Rf+ NH3, are examined with electrical measurements on NiIAu Schottky diodes and CAFM. Current-voltage (IV) mechanisms will identify conduction mechanisms on diodes, and CAFM measurements will investigate the microstructure of conduction in GaN thin films. With CAFM, enhanced conduction has been shown to decorate some extended defects and surface features, while CAFM spectroscopy on a MODFET structure indicates a correlation between extended defects and field

Abstract:

Jádrem této disertační práce bylo studovat optické a elektrické charakteristiky tenkovrstvých elektroluminiscenčních součástek řízených střídavým proudem (ACTFEL) a zejména vliv procesu stárnutí luminiforů na jejich optické a elektrické vlastnosti. Cílem této studie měl být příspěvek ke zvýšení celkové účinnosti luminoforů, vyjádřené pomocí jasu, účinnosti a stability. Vzhledem k tomu, že současnou dominantní technologií plochých obrazovek je LCD, musí se další alternativní technologie plošných displejů porovnávat s LCD.

Abstract:

With the number of transistors integrated into a single integrated circuit (IC) crossing the one-billion mark and complementary metal-oxide-semiconductor (CMOS) technology scaling pushing device dimensions ever-so-close to atomic scales, variability in transistor performance is becoming the dominant constraint in modern-day CMOS IC design. Developing novel approaches for device characterization, which allow a detailed study of electrical transistor characteristics across large statistical sample sets, is crucial for the proper identification, characterization, and modeling of different physica

abstract: In the current photovoltaic (PV) industry, the O&M (operations and maintenance) personnel in the field primarily utilize three approaches to identify the underperforming or defective modules in a string: i) EL (electroluminescence) imaging of all the modules in the string; ii) IR (infrared) thermal imaging of all the modules in the string; and, iii) current-voltage (I-V) curve tracing of all the modules in the string. In the first and second approaches, the EL images are used to detect the modules with broken cells, and the IR images are used to detect the modules with hotspot cells,
