Wachstum und Grenzflächenbeschaffenheit oxidischer Ausscheidungen in Silber
(2003-12-02)The chemical composition of metal/oxide (M/O)- interfaces was studied for an internally oxidized Ag1at.%Mg- and Ag1at.%Mn- alloy with MgO- and Mn3O4- nanoprecipitates in a dilute Ag matrix, ... -
Untersuchungen zur Korngrenzensegregation in nanokristallinen Al-Cu- und Co-P-Legierungen mittels 3d-Atomsondentomographie
(2003-11-28)The objective of this work is the characterization of nanocrystalline Al-Cu and Co-P alloys by means of the tomographic atom probe (TAP) and other characterizing techniques. It is of ... -
Löslichkeit und Diffusion von Wasserstoff in dünnen Schichten amorpher ZrTiNiCuBe- und ZrAlNiCu-Legierungen
(2003-02-12)In this work the solubility of hydrogen in amorphous alloys consisting of more than two elements is investigated theoretically as well as experimentaly. By modelling, the asumption is made ... -
Spannungen, Dehnungen und Lage der Phasengrenzen in dünnen Nb- und Y-Schichten bei Wasserstoffbe- und -entladung
(2002-07-17)In this work the influence of the stresses induced by hydrogen loading on the position of phase boundaries in niobium and yttrium thin films is studied. The films were loaded with hydrogen ... -
Raster-Thermospannungs-Mikroskopie der Interferenz von Elektronenwellen auf der Au(111)-Oberfläche
(2002-02-18)The interference pattern of scattered electron waves is studied for the 2D-electron gas of the Au(111)-surface. For this purpose, the local thermovoltage across the tunneling junction of ... -
Heterogene Interdiffusion von nanokristallinen Cu/Co/Au-Schichten
(2002-01-30)The interdiffusion of Cu/Au-thin films is investigated using several analytical and microscopical methods of high resolution. The main part of the experiments was carried out by means of ... -
Hochauflösende Untersuchung der lokalen Wasserstoffverteilung in metallischen Multischichten mit Hilfe der tomographischen Atomsonde und der Sekundärionenmassenspektrometrie
(2001-11-07)Chemical analyses of hydrogen loaded metallic multilayers on a subnanometer scale using the time-of-flight-methods tomographic atomprobe (TAP) and secondary ion mass spectrometry (SIMS) are reported. The results are discussed ... -
Nanoanalyse der Frühstadien der Interreaktion im System Al/Ni mittels 3D-Atomsondentomographie
(2001-08-07)Metallic multilayers of layer thicknesses of only a few nanometers are attracting an increasing attetntion in industrial applications. The physical properties of such layered systems are ...
