19. Developing an Ar milling process to improve the contact quality to InAs nanowires
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikSammanfattning : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). LÄS MER
20. The Influence of Roughness on Electrical Properties of Single Rock Fractures
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. LÄS MER
