Alternative Buffer-Layers for the Growth of SrBi2Ta2O9 on Silicon
2000
In this work we investigate the influence of the use of YSZ and CeO2/YSZ as insulators for Metal- Ferroelectric-Insulator-Semiconductor (MFIS) structures made with SrBi2Ta2O9 (SBT). We show that by using YSZ only the a-axis oriented Pyrochlore phase could be obtained. On the other hand the use of a CeO2/YSZ double-buffer layer gave a c-axis oriented SBT with no amorphous SiO2 inter- diffusion layer. The characteristics of MFIS diodes were greatly improved by the use of the double buffer. Using the same deposition conditions the memory window could be increased from 0.3 V to 0.9 V. From the piezoelectric response, nano-meter scale ferroelectric domains could be clearly identified in SBT thin…
Energy and range focusing of in-flight separated exotic nuclei – A study for the energy-buncher stage of the low-energy branch of the Super-FRS
2003
Abstract The relative momentum spread of in-flight separated exotic nuclear beams produced in fragmentation and/or fission reactions is of the order of a few percent. A new technique is presented, which reduces the momentum spread significantly, and first experimental results obtained with relativistic projectile fragments are shown. This technique is the key to experiments with slowed-down and stopped beams, in particular for the efficient stopping of relativistic exotic nuclei in gas-filled stopping cells. It will be employed at the energy-buncher stage of the low-energy branch of the Super-FRS facility. The ion-optical design of the energy buncher is presented and a brief outlook to the …
SHIPTRAP—a capture and storage facility for heavy radionuclides at GSI
2002
Abstract SHIPTRAP will be an ion-trap facility for heavy radionuclides delivered from SHIP. Ion traps are a perfect instrument for precision measurements since the ions can be cooled to an extremely small phase space and can be stored for a very long time. In addition one can achieve very high purity by removing contaminant ions. SHIPTRAP will extend the possibilities of measurements in traps to transuranium nuclides and provide cooled and isobarically pure ion bunches.
Die Intensivmedizin in der Sicht des Personals - Ausgangspunkt von Störungen im Intensiv-Team und Faktor des Qualitätsmanagements
2000
Intensivmedizinische Masnahmen werden von den Patienten, den Angehorigen und dem Personal unterschiedlich bewertet. Ein mangelndes Verstandnis fur die Intensivtherapie kann zu einer negativen Einstellung zur Intensivmedizin fuhren, deren Bild in der Offentlichkeit pragen und die Identifikation der Mitarbeiter mit der Intensivmedizin storen.¶ Zur Objektivierung fuhrten wir auf unserer Intensivstation eine Befragung zur medizinischen Technik, zur raumlichen Umgebung, zu allgemeinen medizinischen Fragen und zum Ausmas der intensivmedizinischen Therapie bei 40 Mitarbeitern (11 Arzte, 23 Pflegekrafte, 6 Beschaftigte des Hilfspersonals) durch. Die Dauer der Beschaftigung auf der Intensivstation r…
