1. Nanowire-based InP solar cell materials
Magister-uppsats, Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE); Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)
Författare :Damian Saj; Izabela Saj; [2012]
Nyckelord :nanowire; indium phophide; solar cell; photodetector; electronics; FTIR; semiconductor technology;

Sammanfattning : In this project, a new type of InP solar cell was investigated. The main idea is that light is converted to electrical current in p-i-n photodiodes formed in thin InP semiconductor nanowires epitaxially grown on an InP substrate. Two different types of samples were investigated. LÄS MER

5. Investigation of ZnO nanorods for UV detection
Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)
Författare :David Boban Rihtnesberg; [2011]
Nyckelord :;

Sammanfattning : In recent years, there has been increasing interest in ZnO semiconductors for optoelectronic application in the UV wavelength region due to its large exciton binding energy of 60 meV and wide bandgap energy of 3,37 eV at room temperature. One-dimensional ZnO nanostructures such as nanorods or nanowires have been considered as promising candidates for UV sensing and detecting applications owing to its high surface to volume ratio.
