1. Adventures of III-V Semiconductor Surfaces
Sammanfattning : Tailoring the surface composition and morphology of materials to enable new electronic devices is important for a wide range of applications such as quantum computing or spintronics. A fundamental understanding of the changes induced in the surface during different process steps can help to establish new synthesis routes as well as devices. LÄS MER
2. Electronic Structure of Some Zincblende Semiconductor Surfaces
Sammanfattning : The main aim of this thesis is to study and understand the surface electronic structure of compound semiconductors (ex. GaAs, InP, ..etc. LÄS MER
3. Atomic and Electronic Structure of III-V Semiconductor Surfaces
Sammanfattning : The atomic and electronic structure of clean and Cs-perturbed III-V semiconductors was studied by angle-resolved photoelectron spectroscopy (ARPES), surface core level spectroscopy (SCLS), and scanning tunneling microscopy (STM). The work can be divided into three parts, dealing with low-index sur-faces, high-index surfaces, and special features of InAs. LÄS MER

5. III–V Nanowire Surfaces
Sammanfattning : This dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS).
