1. Metamorphic Heterostructures and Lasers on GaAs
Sammanfattning : The objective of this thesis is to demonstrate the metamorphic growth of heterostructure lasers on GaAs substrates. Many heterostructure devices have their performance limited by the need to grow on lattice-matched substrates. LÄS MER
2. Elements of AlGaN-Based Light Emitters
Sammanfattning : The III-nitrides have enabled a range of optoelectronic devices and associated applications of great industrial and societal importance. However, the full potential of the III-nitrides remains to be explored. LÄS MER
3. High performance materials and processing technology for uncooled 1.3 μm laser diodes
Sammanfattning : This thesis investigates different material systems and processing technology for high temperature compatible laser diodes used in volume applications within the 1.3-μm telecom wavelength window. LÄS MER
4. Towards Novel AlGaN-Based Light Emitters
Sammanfattning : The unique properties of the AlGaN semiconductors make them a suitable choice for optoelectronic devices at both short and long wavelengths, based on interband and intersubband transitions, respectively. What sets AlGaN apart from other wide-bandgap semiconductors is the possibility to obtain both p- and n-type conductivity as well as the direct bandgap. LÄS MER
