Bone is a complex and very important multi-constituent bio-composite. In this work, we focus on the arrangement of bone constituents from the nanoscopic to the microscopic scale, and investigate the influence of their arrangements on the fracture mechanism ...
With the recent technological advances, there is an increasing need for measurement systems providing interferometer resolution for inspection of large quantities of individual samples in manufacturing environments.. Such applications require high measurem ...
Information for phase identification may be gathered in the electron transmission microscope with spatial resolution down to the nanometre scale. Energy dispersive X-ray and electron energy loss spectrometries are based on inelastic electronsample interact ...

A release technique that enables to lift microfabricated structures mechanically off the surface without using wet chemistry is presented. A self-assembled monolayer of dodecyltrichlorosilane forms a very uniform 1.5-nm-thick anti-adhesion coating on the s ...
Scanning tunneling microscopy (STM) is used in situ to study threading dislocation terminations at the surface of GaN grown by molecular beam epitaxy on a Si(111) surface. The associated surface depressions are imaged at the nanometer scale, giving a new i ...
The development of nanosystems and nano-devices demands for patterning methods in the nanoscale. To bring them to the market, there is a need for fast, low-cost nanopatterning methods. In addition, an increased flexibility is important for the engineering ...
Periodic polarity (PePo) GaN films are grown by molecular-beam epitaxy. A high Mg doping is used to reverse the film polarity from Ga to N. An etching step is then performed to define the PePo pattern. Ultrasharp inversion domain boundaries between Ga- and ...
Digital holographic Microscopy (DHM) is an imaging modality reconstructing the wavefront in a numerical form, directly from a single digitalized hologram. It brings quantitative data derived simultaneously from the amplitude and phase of the complex recons ...
Recombination dynamics in InGaN/GaN quantum wells has been studied by time resolved photoluminescence (PL). The radiative recombination processes in these systems can be qualitatively explained on a nanometer-scale by a model based on the recombination dyn ...
