Nanostencil lithography is a flexible, rapid and resistless patterning method based on a high-resolution shadow mask. It allows for a wide choice of materials and surfaces to be structured and on the contrary to deep-ultraviolet (DUV), x-ray, electron beam ...
The topic of this dissertation is embedded into the new-born field of inorganic nanowires. The research was focused on zinc oxide (ZnO) nanowires, in particular, which besides posing fundamental questions in physics, promise broad range of applications. Zn ...
Nanocrystalline metals have been an area of great interest in recent years due to their enhanced characteristics. One of the most striking is implied by the Hall-Petch relation: with decreasing grain size the material becomes stronger. This promise is fulf ...
Flexures are mechanical elements used in micro- and precision-engineering to precisely guide the motion of micro-parts. They consist of slender bodies that deform elastically upon the application of a force. Although counter-intuitive at first, fused silic ...
Single crystal deformation unveiling the characteristics of crystal glide and the role of defect propagation herein has been a matter of intense research more than 60 years ago. A manifold of different mechanical testing methods and crystal qualities were ...
For the past couple of decades the desire to add more complexity to a computer chip, while simultaneously reducing the cost per bit, has been accommodated by down-scaling. This approach has been extremely successful in the past, but like all good things it ...
Stencil lithography is a surface patterning technique that relies on the local physical vapor deposition of material through miniaturized shadow mask membranes. It is extremely useful for the formation of patterns, mainly thin structured metal films, in si ...
Cantilever-based detection of ultrasmall forces is of great interest for several applications such as magnetic resonance force miscroscopy (MRFM) where an ultrahigh sensitive cantilever is used to detect magnetic resonance in small ensembles of electron or ...
Increased flexibility of patterning methods is important for the engineering of multimaterial and multifunctional nano/micro-electro-mechanical systems (NEMS/MEMS), such as polymer-based electronic and sensor devices, 3D microfluidic systems, and bio-analy ...
Irradiation is known to lead to a degradation of the mechanical properties of materials. This is particularly crucial in the case of materials that will be used in the future thermonuclear fusion reactor, where extremely high irradiation doses are expected ...
