Opis:
Scanning probe microscopy (SPM) since its invention in the 80’s became very popular in examination of many different sample parameters, both in university and industry. This was the effect of bringing this technology closer to the operator. Although the ease of use opened a possibility for measurements without high labour requirement, a quantitative analysis is still a limitation in Scanning Probe Microscopes available on the market. Based on experience of Nano-metrology Group, SPM still can be considered as a tool for quantitative examination of thermal, electrical and mechanical surface parameters. In this work we present an ARMScope platform as a versatile SPM controller that is proved to be useful in a variety of applications: from atomic-resolution STM (Scanning Tunnelling Microscopy) to Multi-resonance KPFM (Kelvin Probe force microscopy) to commercial SEMs (Scanning electron microscopes).

Opis:
In this paper we summarize the results of our research concerning the diagnostics of micro- and nanostructure with scanning probe microscopy (SPM). We describe the experiments performed with one of the scanning probe microscopy techniques enabling also insulating surfaces to be investigated, i.e., atomic force microscopy (AFM). We present the results of topography measurements using both contact and non-contact AFM modes, investigations of the friction forces that appear between the microtip and the surface, and experiments connected with the thermal behaviour of integrated circuits, carried out with the local resolution of 20 nm.

Opis:
W pracy przedstawiono wybrane metody analizy powierzchni (ISO 25178) wskazując na rodzaj informacji, jaką można za pomocą danej metody uzyskać. Opisywane algorytmy i procedury zostały zaimplementowane w opracowanym w Wydziałowym Zakładzie Metrologii Mikro- i Nanostruktur Politechniki Wrocławskiej programie TOPOGRAF. W pracy zaprezentowano przykładowe wyniki działania zaimplementowanych algorytmów i procedur.
Progress in the scanning probe microscopy makes it become a much more common tool. In the paper the principle of operation of the scanning probe microscope is presented. It is emphasized that the measurement result is an image of the investigated surface. Two groups of parameters connected with lateral properties of the tested surface image are introduced. The first group of parameters is connected with the image autocorrelation function and two dimensional Fourier transform. The texture aspect ratio and surface autocorrelation length (Fig. 1) are given as examples of the autocorrelation parameters. The second group of parameters is related to the so called 3D motif analysis. At the first stage of this analysis the image is segmented by means of the watershed segmentations algorithm. At the second stage the statistics connected with the shape and dimensions of the segments are calculated. The segmentation algorithm as well as the parameters describing shape and dimensions of segments (Fig 2) are presented in the paper. Due to the quantum nature of the micro- and nano-world, the uncertainty of products of the micro and nanotechnology will always be greater than that of products of the conventional technology. For this reason there is strong demand for flexible techniques capable of handling this increased uncertainty. The 3D motif analysis is very well suited to meet this challenge, since it enables the extension of the basic set of the parameters describing segments. Therefore the segment parameters might be adapted to the function of the investigated nanostructures. The images presented in the paper were obtained by means of the TOPOGRAF software that is developed at the Division of Micro- and Nanostructures Metrology.

Opis:
Scanning tunneling spectroscopy was used to check the tunneling I-V characteristics of junctions formed by n-ZnO nanowires deposited on Si substrates with n- and p-type electrical conductivity (i.e. n-ZnO nanowire/n-Si and n-ZnO nanowire/p-Si junctions, respectively). Simultaneously, several phenomena which influence the measured I-V spectra were studied by atomic force microscopy. These influencing factors are: the deposition density of the nanowires, the possibility of surface modification by tip movement (difference in attraction forces between nanowires and the p-Si and n-Si) and the aging of the surface.

Opis:
The surface roughness of the dental restorations is significant to the denture plaque adhesion. Methods: In this work, we present the complex analysis of the electropolished CoCrW alloy remanium® star (Dentaurum, Germany) samples with laserengraved fiducial marks performed using complementary set of micro- and nanoscopic techniques: optical profilometry (OP), atomic force microscopy (AFM), scanning electron microscopy (SEM) and focused ion beam (FIB) milling. Results: Both mean and RMS roughness of the samples were reduced by electopolishing process, however, the results obtained using OP and AFM exhibited some discrepancies. This was caused by the relatively high local protruding defects developed on the processed surface. The cross-sections of the protrusions were made to analyze the cause of their formation as the EDS elemental content maps revealed that their composition was uniform. We also analyzed the local roughness in the smaller areas free from the defects. Conclusions: In that case, both OP and AFM techniques delivered the same results. Analysis of results showed that various methods used for the surface roughness evaluation have to be used simultaneously to obtain complete and true analysis of the technological CoCrW samples.

Opis:
In this paper, we present a simple near-field probe model that is composed of an elongated ellipsoid and a finite metal truncated cone. The elongated ellipsoid has been shown to act as a protrusion or separate particle near a truncated cone apex with strong near-field enhancement under laser excitation. By controllably varying the length of the ellipsoid protrusion from the truncated cone, the truncated cone-ellipsoid probes can be adapted to the suitability of near-field probes. The effects of substrate material and excitation wavelength on the near field enhancement for different tip apexes are also discussed. In addition, we compared the properties of the truncated cone-ellipsoid probe with the widely used hemisphere conical tip by launching surface plasmon polaritons on plasmonic waveguides to prove the suitability of the truncated cone-ellipsoid probes as high performance near-field probes. The present simple model would provide a theoretical basis for the actual construction of probes.
