1. Perfusion Monitoring of Advancement and Rotational Flaps. Oculoplastic Surgery and Laser Speckle Contrast Imaging
Sammanfattning : Flaps are widely used in oculoplastic reconstructive surgery to cover defects following the removal of tumors, malformations, or trauma. Adequate blood perfusion of the flap is crucial for its survival. Knowledge about the perfusion in different type of flaps is therefore of great value. LÄS MER
2. From Light to Dark : Electrical Phenomena in Cu(In,Ga)Se2 Solar Cells
Sammanfattning : In Cu(In,Ga)Se2 (CIGS) solar cells the CIGS layer serves as the light absorber, growing naturally p-type. Together with an n-type buffer layer they form a p-n heterojunction. Typically, CdS is used as a buffer, although other, less toxic materials are investigated as alternatives. LÄS MER
3. On Generation and Recombination in Cu(In,Ga)Se2 Thin-Film Solar Cells
Sammanfattning : The solar cell technology based on Cu(In,Ga)Se2 (CIGS) thin-films provides a promising route to cost competitive solar electricity. The standard device structure is ZnO:Al/ZnO/CdS/CIGS/Mo films on a glass substrate, where the first three layers are n-type semiconductors with wide bandgaps, forming a pn-junction with the p-type CIGS absorber layer; the Mo layer serves as a back contact.

4. Modulations in B8-type Intermetallics
Sammanfattning : The B8-type regions of the Mn-Sn and Cu-In systems have been investigated by means of electron and X-ray diffraction. The importance of the combination of these techniques in the study of B8-type phases is pointed out. In addition to the B8-type phases an alloy with a quasicrystal approximant structure has been studied. LÄS MER
5. Metal release from powder particles in synthetic biological media
Sammanfattning : Humans are exposed to metals and metal-containing materials daily, either conscious, e.g. using metal tools or objects, or unconscious, e.g. LÄS MER
