Nanoscopic Characteristics of Anhydrite (100) Growth

Nanoscopic characteristics of anhydrite (100) surface growth under mild hydrothermal conditions

Anhydrite (CaSO4) is a major component of evaporitic rocks and is currently forming in submarine hydrothermal fields, where its dissolution and precipitation plays a significant role in controlling porosity. Anhydrite also is a component of undesirable scale on heat transfer surfaces during desalinization and waste water treatments. Knowledge of the molecular processes that control anhydrite gr...

1 Epitaxial growth of Cu ( 100 ) and Pt ( 100 ) thin

Pulsed laser deposition (PLD) has been used to grow epitaxially oriented thin films of Cu and Pt on (100)-oriented substrates of both SrTiO3 and LaAlO3. The resulting films have been characterized for their crystalline orientations using x-ray diffraction (XRD) and for their surface morphologies using atomic force microscopy (AFM). The diffraction results illustrated that purely epitaxial Cu(10...

Spectroscopy of nanoscopic semiconductor rings.

Making use of self-assembly techniques, we realize nanoscopic semiconductor quantum rings in which the electronic states are in the true quantum limit. We employ two complementary spectroscopic techniques to investigate both the ground states and the excitations of these rings. Applying a magnetic field perpendicular to the plane of the rings, we find that, when approximately one flux quantum t...

Nanoscopic Evaluation of Micro-systems

Due to their complex tasks micro-systems are affected in their performance by the local variation of material parameters like mechanical, thermal, optical, electronic and electrical properties. As the active areas of micro-systems are not only in the micrometer range, but in the submicron or nanometer range, evaluation of these features has to be carried out with corresponding spatial resolutio...
