The shape and dimensions of an atomic force microscope tip are crucial factors to obtain high resolution images at the nanoscale. When measuring samples with narrow trenches, inclined sidewalls near 90 or nanoscaled structures, standard silicon atomic forc ...
This paper reports on the design, fabrication and optical characterization of a self-aligned microlaser scanning system consisting of a vertical cavity surface emitting laser (VCSEL) source and a MEMS-actuated microlens scanner. The alignment and the spaci ...
Laser scanning is commonly used in railways for detecting problems related with the clearance profile which are quite common especially in old tunnels. By increasing the resolution of the scanner system it is possible to use the images for identifying prob ...
A detailed structural analysis of the surface supported self-assembly of terphenyl-4,4′′-dicarbonitrile molecules (NC−Ph3−CN) linked by Co adatoms on Ag(111) reveals different surface patterns depending on the constraints applied to the system. Without con ...
The control of light emission on the scale of individual quantum systems, like molecules or quantum dots, is a field of intense current research. One way to induce light emission from these systems is the local charge injection through the tip of a scannin ...
In laser micro-manufacturing, one of the challenges is to achieve fast scanning speed for fast fabrication of complex 3D microstructures. For microstructures with nanoscale features, it is often desirable to steer laser beams from a few microns to a few te ...
A detailed investigation and characterization of the local properties of individual nanoscopic structures is of great importance for the understanding of novel physical phenomena at the nanoscale as well as for the assessment of their possible use in futur ...
NOVELTY - The microscope (11) has a set of four actuators (14, 16, 18, 20) i.e. piezoelectric actuators, and a strain gauge coupled to two opposed actuators (14, 18), arranged in opposed push or push-pull configuration to measure the differential motion of ...
NOVELTY - The scanning method involves generating data signal using a sensor. The first component based on a motion in a first direction of an actuator configured to provide motion between a sample and a probe in the first direction, the first direction su ...
The growth of rubrene (C42H28, 5,6,11,12-tetraphenylnaphthacene) multilayer islands up to a thickness of six layers on a Au(111) surface has been investigated by scanning tunneling microscopy. The molecules self-organize in parallel twin rows, forming mirr ...
