Solid state lighting is a new environmentally friendly light source. So far, light emitting diodes (LEDs) and organic LEDs (OLEDs) have been presented as candidates with potentially high efficiency. Recent advances of OLEDs in device architecture, light-out coupling, and materials have ensured high efficiency, exceeding that of incandescent light bulbs. In contrast to conventional point source LEDs, OLEDs distribute light throughout the surface area and are not restricted by their size. Additionally, OLEDs are expected to reach sufficient stability in the near future. The remaining challenge for OLEDs is their cost. New OLED technologies provide cost effective manufacturing methods which could be presented for transparent electrode materials because indium tin oxide (ITO), a widely used material as a transparent electrode for OLEDs, is less than optimal due to its high element price. In this work, alternative transparent electrodes for OLEDs as a replacement of ITO were studied. First, Al doped ZnO (ZnO:Al) which is composed of abundant materials was investigated with DC magnetron sputtering under a wide range of experimental conditions. The optimised ZnO:Al received comparable performance with conventional ITO films, low sheet resistance of 22.8 Ω/sq as well as a high transparency of 93.1 % (average value in the visible range). Various type of p-i-n OLEDs were employed on the structured ZnO:Al using photolithography. Green OLEDs with double emission layers have been archived stable efficiencies even at higher luminance. Also, OLEDs using two fluorescent colour system on ZnO:Al anode showed a purely white emission. It has been found that the OLEDs on ZnO:Al anode has comparable or better device efficiencies and operational lifetime compared to OLEDs on conventional ITO anode. As another alternative electrode, the conductive polymer Baytron®PH510 (PEDOT:PSS) was investigated. Due to a relatively high sheet resistance of PEDOT:PSS, metal grid was designed for large size OLEDs. White OLEDs on PEDOT anode with a size of 5 × 5 cm2 have achieved more than 10 lm/W of power efficiency using a scattering foil. Furthermore, up-scaled devices on 10 × 10 cm2 were also demonstrated. These results showed ZnO:Al and PEDOT are suitable for OLEDs as anode and have high potential as alternative transparent electrode materials.

Les oxydes transparents conducteurs (TCO) ont la rare propriété de concilier haute transparence et conductivité élevée, ce qui en fait des matériaux-clés pour de nombreuses applications requérant des électrodes transparentes comme les cellules photovoltaïques, les diodes organiques et les écrans plats. Avec une résistivité de l'ordre de 10^(-4) ohm.cm et une transmittance de 85% dans le domaine visible, l'oxyde d'indium dopé à l'étain (ITO) est le matériau privilégié. Toutefois, sa fragilité, son instabilité aux procédés plasma et son coût croissant du fait de sa haute teneur en indium sont autant de raisons de rechercher des matériaux alternatifs. Cette thèse a pour but de comprendre les points clefs permettant d'améliorer les performances d'une électrode transparente en oxyde de zinc dopé à l'aluminium (AZO) sur les plans optique, électrique et au niveau des interfaces ; des cellules photovoltaïques en silicium amorphe hydrogéné (a-Si:H) servent de dispositif-test à cette étude. Réalisées par pulvérisation cathodique magnétron sous des conditions de dépôt variées, les couches minces d'AZO obtenues ont une structure microcristalline et, pour des paramètres déterminés, des performances optoélectroniques approchant celles de l'ITO. Un modèle adapté d'après la théorie de Drude a permis de rendre compte du lien entre transparence et conduction et de confirmer la saturation en porteurs du matériau. L'efficacité d'une électrode au sein d'un dispositif dépend également très fortement de l'interface entre celle-ci et l'absorbeur, les porteurs devant être extraits rapidement pour ne pas se recombiner. Quelques voies ont été explorées pour réduire la barrière de potentiel entre le silicium amorphe et l'électrode tout en favorisant l'efficacité optique des cellules. Il ressort que l'insertion d'une couche tampon d'oxyde de titane ou de tungstène permet d'obtenir un gain notable dans les performances des cellules.

Já os seus óxidos são muito utilizados na confecção de baterias automotivas, pelo seu comportamento condutor. Dos vários óxidos de chumbo que existem, o dióxido de chumbo (PbO2) é um dos que mais se destacam devido a suas aplicações. O β-PbO2 é um semicondutor com band gap estreito, que recebeu uma grande atenção ultimamente devido à sua potencial utilização como óxidos condutores transparentes (TCO). Os TCO são compostos que combinam as propriedades normalmente mutuamente excludentes da transparência e da condutividade. O desempenho óptico e elétrico dos TCO está intimamente ligado à estrutura de bandas e, desta forma, a distribuição periódica de potencial em um cristal. Neste trabalho procura-se compreender os fundamentos das propriedades elétricas macroscópicas do material β-PbO2 na forma de filmes finos. Para tanto, adotou-se abordagem da mecânica quântica baseada na Teoria do Funcional Densidade (DFT), com potencial híbrido B3LYP, implementada no código CRYSTAL09. Cálculos de estrutura de bandas e densidade de estados mostram que o band gap de filmes de β-PbO2 tendem para o gap do material na forma de bulk e cálculos de energia de superfície permitem concluir que sua face mais estável é a (110). / Lead, due to its high resistivity, is a poor conductor of electricity and is classified as a semiconductor. On the other hand their oxides are widely used in the manufacture of automotive batteries, because of its conductivity. β-PbO2 is a narrow band gap semiconductor which received great attention lately due to their potential use as a transparent conducting oxide (TCO). The TCO are compounds which combine transparency and conductivity, properties that normally do not coexist. The optical and electrical performance of the TCO are intimately connected to the band structure and thus the potential distribution in a periodic crystal. This work, seeks to contribute for understanding the fundamentals of macroscopic electrical properties of β-PbO2 material in the form of thin films. Therefore, it was adopted the quantum mechanics approach based on Density Functional Theory (DFT), with B3LYP hybrid potential, implemented in the CRYSTAL09 code. Band structure and density of states calculation show that the band gap of β-PbO2 films tend to the bulk band gapsurface energy calculations permit conclude that its most stable face is the (110).

This thesis gives an example of how decision analytic methods can be applied to choices in the adoption of cloud computing. The lifecycle of IT systems from planning to retirement is rapidly changing. Making a technology decision that can be justified and explained in terms of outcomes and benefits can be increasingly challenging without a systematic approach underlying the decision making process. It is proposed that better, more informed cloud adoption decisions would be taken if organisations used a structured approach to frame the problem to be solved and then applied trade-offs using an additive utility model. The trade-offs that can be made in the context of cloud adoption decisions are typically complex and rarely intuitively obvious. A structured approach is beneficial in that it enables decision makers to define and seek outcomes that deliver optimum benefits, aligned with their risk profile. The case study demonstrated that proven decision tools are helpful to decision makers faced with a complex cloud adoption decision but are likely to be more suited to the more intractable decision situations.
