Sammanfattning : Ultraviolet (UV) light sources have a direct impact on everyone’s life. They are used to sterilize surfaces as well as for water purification. In addition, they are used in green houses to enhance health-promoting substances in plants, for phototherapy to treat skin diseases, for sensing and material curing. LÄS MER
Sammanfattning : Coherent extreme ultraviolet (XUV) light sources are necessary for the investigation of physical processes in the natural length and time scales of atoms. These experiments require a high degree of control of the coherent XUV light. LÄS MER
Sammanfattning : Cataract is the leading cause of blindness in the world. Epidemiological and experimental evidence supports a link between mid-range ultraviolet radiation (UVR-B) exposure and the development of cataract. LÄS MER
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
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
