Optical characterization of patterned nanowire arrays using solid immersion microscopy

Abstract
The nanowires technology has proved itself to be fairly promising in
order to develop more ecient optoelectronic devices such as solar cells
and LEDs. It becomes therefore interesting to be able to characterize
nanowires samples with a high precision, so that the light emitted from
each single nanowire can be detected and analyzed. The purpose of
this thesis project was to test if solid immersion microscopy represents
a valid tool in order to increase the resolution of optical microscopy
enough to distinguish between single nanowires in arrays. A solid im-
mersion lens was fabricated, and then it was tested on a number of
dierent samples in order to characterize it and to compare the re-
sults with the ones obtained by standard... (More)

immersion microscopy led generally to a higher resolution in case of
white light images. Photoluminescence and electroluminescence mea-
surements were also performed; even though the experimental real-
ization of such measurements was somehow trickier, solid immersion
microscopy provides room for further improvements in resolution. (Less)
