Trójmiejski Landscape Park
Opis:: The paper presents the results of erratic boulders studies in the area of Trójmiejski Landscape Park (TLP) located west of the Gulf of Gdañsk. The research objects were boulders protected as natural monuments (66 erratics) and all boulders with long axis ³ 50 cm within two testing areas (1100 erratics). Results show that erratics of the TLP often occur in clusters and their spatial density is even near 300 items/km2 in some areas. The authors selected 44 boulders which may be interesting research objects and/or have high values for geotourism. Nine erratics reveal features potentially suitable for the terrestrial cosmogenic nuclides (TCN) dating. Moreover, high number of boulders in the TLP area gives the possibility for investigations of the directions of glacial paleo-transport based on indicator erratics and analysis of glacial striae. Distinctive zones of significant clusters of boulders characterised by high attractiveness and diversified values were also indicated.

Opis:: The atomic structure and morphology of ultrathin Pb layers deposited on the Ni(001) face in ultrahigh vacuum at the substrate temperature, ranging from 145 K to 900 K, were investigated with the use of the Auger electron spectroscopy and low-energy electron diffraction. The analysis of the Auger electron spectroscopy measurements indicates that the Volmer-Weber growth of the Pb takes place for substrate temperature T < 300 K. Between 300 and 600 K, the Stranski-Krastanov growth mode is observed. For 600 K ≤ T ≤ 700 K, only first two-dimensional Pb layer formation is found. Above 700 K desorption of lead atoms from the first layer is observed. The ordered low-energy electron diffraction patterns corresponding to p(1×1) and c(2×2) structures are observed.

Opis:: In the present study the thermal behavior of ultrathin Au films deposited on different noble metal single crystal surfaces was studied by means of ultraviolet photoelectron spectroscopy and photoemission of adsorbed xenon. The primary goal of this work was to demonstrate the power of photoemission of adsorbed xenon as an easy to handle and very surface sensitive technique for the characterization of multi-component systems. All investigated systems, Au-Pt(111), Au-Pd(111) and Au-Pd(110) show a particular dependence of their electronic and structural properties on the annealing temperature. Au multilayer films with a thickness of 3 monolayer prepared at 150 K undergo in all cases a smoothening by annealing up to room temperature. While on Pd this effect is mainly detectable on the topmost atomic layer the ordering process on Pt is also affecting the deeper layers. Further annealing of the Au-Pd system to 450 K and the Au-Pt system to 750 K, respectively, results in the onset of the alloying process at the interface between metal film and substrate. After annealing to 650 and 950 K, respectively, the alloying finally extends to the very surface. The complete loss of Au from the surface can be detected at 1050 K on Pd and at 1150 K on Pt. The orientation of the substrate has only a weak influence, showing up e.g. in additional electronic states of the not alloyed Au-Pd(111) and Au-Pd(111) systems. Adsorption of CO as a probe molecule illustrates the formation of different adsorption sites on the bimetallic systems during the Au diffusion process.
