The impact of different carbon concentrations in the Al 0.06 Ga 0.94 N graded back-barrier and GaN buffer of high electron mobility transistors (HEMTs) is investigated. Four epi-wafers with different carbon concentrations, ranging from 1 × 10 17 to 5 × 10 17 cm −3 , were grown by metal organic chemical vapor deposition (MOCVD). HEMTs with 100 and 200 nm gate lengths were fabricated and characteriz

Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an alternating current bias can tune the response of such a diode. We show that for slow driving there is always a regime where the system can only carry zero-voltage dc current in one direction, thus effectively behaving as an i

The archivist Martin Grass defines personal archives as that they do not have to adapt to guidelines when it comes to the culling or preservation of the material, the submitting of the material to an archive is not done directly after the material is created or collected and that they often concern broader subjects. In this thesis I study the creator of the personal archives and the driving forces

Vägar slits konstant och kräver konstant förbättringar och ombyggnationer. För att möjliggöra detta krävs personer som befinner sig ute på vägarna. Tekniken har gått framåt inom området trafiksäkerhet men skulle behöva förbättras ytterligare om vägarbetare ska vara säkra på sin arbetsplats. Även trafiken har förändrats över åren. Idag finns fler fordon på vägarna än aldrig förr. Bilarna är säkrareRoads are constantly worn down and demands improvements and reconstructions. To make this possible there has to be road workers on the road. Road safety has been improved along the years but can still be improved more. Today there are more vehicles on the road than ever before. The cars are more safe and therefore is encouraging to higher speeds as they are driven together with all safety features

Inom marknadsföring är det en ständig kamp att framställa varumärken som det bästa där det är vanligt att locka med diverse gåvor och belöningar för att försöka få lojala kunder. Syftet med studien var att undersöka om en belöning (choklad) kunde påverka studenters attityd gentemot designen på olika reklambilder. Närmare bestämt om attityden kunde påverkas av belöningen men också om det skiljer siWithin marketing there is a constant struggle to promote brands as the best and it is common practice to promise various gifts and rewards in an attempt to attract loyal customers. The purpose of the study was to investigate whether a reward (chocolate) could influence students' attitudes towards different ads. Specifically, if the attitude could be influenced by the reward but also if it diff

Internet of Things (IoT) is network constituted by day-to-day objects equipped with some sensing system. These objects can also communicate with other objects for data exchange, wirelessly. This calls for a need of better wireless communication systems. New techniques using the 4G (Long-Term Evolution) have been developed to solve this problem, known as Advanced Antenna System (AAS). This new tech

This study focus on the six largest minable cryptocurrencies: Bitcoin, Bitcoin Cash, Litecoin, Ethereum, Monero and DASH, and puts forward determinants that explain large parts of the price value formation in the markets. This is done by Ordinary Least Squares linear regression with intent to validate or question previous research regarding explanatory factors driving the market price. These facto

In this master’s thesis I will investigate how librarians think about how their profession is affected by and relates to the democratic mission and various cultural policy decisions. I will also attempt to make more clear how librarians interpret, relate and deal with external forces of change such as technology, politics and other social forces. This has been done to investigate and survey the tw

In Swedish, adverbials mainly occur in two positions in the clause: postverbally (last in the clause) or medially (before the finite verb in subordinate clauses and after the finite verb but before e.g. infinite verbs in main clauses). VP adverbials are said to have their natural position postverbally, but they can also be placed medially. This thesis examines factors that influence the placement

Sustainability reporting has become the primary measure of corporate sustainability in the EU, with increasing awareness among companies about the importance of disclosing sustainability matters. Concurrently, the European Union has enacted several pieces of legislation regarding sustainability reporting, notably the Corporate Sustainability Reporting Directive. While blockchain technology initial

The dramatic shifts that occurred to the Chinese economy in the recent decades led to the emergence of companies that have fulfilled the internal market needs and now try to compete on the global level. Among others, Chinese automotive industry is currently struggling to establish its products in the markets of developed countries; however, the results are modest due to low level of technological

Abstract Gathering information about the environment is crucial to living organisms as it makes up the foundation upon which decisions are made. In a diverse environment a huge amount of information sources arise. An individual can choose to follow other’s decision (social information use) or to gather its’ own information. Which sources are used and how well they are perceived vary between indi

The French semantic Roland Barthes belives that within our language there exists myths. These myths, being highly suggestiv, creates an alternative lingustic property beyond words actual meaning. However, Barthes belived that myths are hard to apply to political science, and further more, claimng that myths doesnt manifest itself within the socialist ideology. By using Arthur Koestlers masterwork
