Konferensbidrag (refereegranskat)abstract
- A fluorescence lidar measurement has been performed on the castle Övedskloster in Sweden. A mobile system from the Lund University was placed at ~40 m distance from the sandstone façade. The lidar system, which uses a frequency-tripled Nd:YAG laser with a 355-nm pulsed beam, induces fluorescence in each target point. Areas were studied by using whisk-broom scans. The possibility of detecting biodeteriogens on the surface and characterization of materials was confirmed. The method can be a tool for conservation planning and status control of the architectural heritage where fluorescence light can point out features that are not normally visible under natural illumination.

Cathodoluminescence Studies of AlGaAs/GaAs Core-Shell Nanowires
- 2005
-
Ingår i: Springer Proceedings in Physics. - 0930-8989. ; 107, s. 463-466

Konferensbidrag (refereegranskat)abstract
- We have studied nanowires with a GaAs core, covered by an AlGaAs shell, using low temperature cathodoluminescence. The main emission from the core is due carbon acceptors, though we observe a weak emission from excitons. A general observation is that the emission is much stronger from the top half of the nanowire. This emission is also more well-defined. The AlGaAs shell emission varies in emission energy and spatial origin in an irregular fashion.

Structural Characterisation of GaP <111 > B Nanowires by HRTEM

- GaP < 111 > B nanowires are dominated by (111) twins orthogonal to the growth direction and show well-developed {111} side-facets. Based on this, a 3D-model has been constructed with a cross-section of an octahedron used as a building block. The twins can be of ortho- or para type i.e. by 60 degrees about the growth axis or 180 degrees in the twin plane. The segment thickness variation follows an exponential distribution with a clear dependence oil growth ternperature. Multislice simulations show different features of the twin types that are useful for further characterisation.
