1. Electron Transport in Semiconductor Nanowires
Sammanfattning : In this thesis, semiconductor nanowires are studied from the point of view of growth and electrical properties. The growth of nanowires is done by chemical beam epitaxy (CBE), an ultra-high vacuum technique allowing a precise control of precursor deposition and low growth rates. LÄS MER
2. Growth, Physics, and Device Applications of InAs-based Nanowires
Sammanfattning : This thesis is based on three different projects: 1) the epitaxial growth of nanowires using chemical beam epitaxy, 2) the study of electron transport through quantum dots and multiple quantum dots in nanowires at low temperature, and 3) the development of wrap gated nanowire field effect transistors. In the first part, a method of studying the diffusion of the source material on the substrate surface was developed. LÄS MER
