4. InGaAs-based quantum dots for infrared imaging applications : growth and characterisation
Sammanfattning : In this thesis, results are presented from the development of quantum dot (QD) based infrared photodetectors (IPs). This includes epitaxial growth of QDs, investigations of the structural, optical and electronic properties of the QD based material as well as characterisation of the resulting components. LÄS MER
5. Growth and Characterization of Strain-engineered Si/SiGe Heterostructures Prepared by Molecular Beam Epitaxy
Sammanfattning : The strain introduced by lattice mismatch is a built-in characteristic in Si/SiGe heterostructures, which has significant influences on various material properties. Proper design and precise control of strain within Si/SiGe heterostructures, i.e. LÄS MER
