    Electrical characteristics of Ti-Ta-O based MIM capacitors

    Journal of Vacuum Science & Technology B, vol. 29, no. 1

    2011

    DOI: 10.1116/1.3534020

    Abstract anzeigen

    Amorphous Ti–Ta–O thin films were deposited by the atomic-vapor deposition technique for metal-insulator-metal (MIM) applications. Depositions were carried out at 400 °C on 200-mm Si (100) wafers using TiN and TaN as bottom electrode materials. The comparison of electrical properties of MIM capacitors was done after physical-vapor deposited growth of different top electrodes, namely, Au, TiN, TaN, and Ti. Capacitance-voltage measurements revealed that the dielectric constant of 50 can be reached if Ti–Ta–O layers are deposited on TiN and if Au, TaN, or Ti is used as the top electrode. The k value is reduced to 37 if TaN is used as bottom electrode. However, if TiN is used as the top electrode, the k value of the stack is reduced by a factor of 3, from 50 to 17, independent of whether TiN or TaN are used as bottom electrodes. The lowest leakage current values (∼10−8 A/cm2) were observed when gold was used as the top electrode, whereas it increased by 3 orders of magnitude if the top electrode was changed to TiN and even more if the top electrode was changed to TaN or Ti.

    A numerical study of impact force caused by liquid droplet impingement onto a rigid wall

    Progress in Nuclear Energy, vol. 53, no. 7, pp. 881-885

    2011

    DOI: 10.1016/j.pnucene.2011.03.002

    Abstract anzeigen

    Liquid droplet impingement (LDI) erosion could be regarded to be one of the major causes of unexpected troubles occasionally occurred in the inner bent pipe surface. Evaluating the LDI erosion is an important topic of the thermal hydraulics and structural integrity in aging and life extension for nuclear power plants. One of the causes of LDI erosion is the impact pressure by the impingement of droplets in the involved steam. We investigated a simple droplet impingement to a rigid wall using volume of fluid (VOF) model, which is a two-phase Eulerian–Eulerian approach. The impact of a single water droplet with a high velocity towards a solid surface is examined numerically. The high Reynolds number value implies inertia dominated the phenomena and supports an inviscid approach to the problem. The high Weber number is justifying that an assumption to neglect the surface tension effect is adopted. We show that the compressibility of the liquid medium plays a dominant role in the evolution of the phenomenon. Both generation and propagation of shock waves are directly computed by solving the fluid dynamics continuity and momentum equations. In the simulation we employed a front tracking solution procedure, which is particularly suitable for two-phase free surface computation. The numerical results show that critical maximum pressure is not highest at the center of droplet contact on the surface at the first instantaneous moment but highest behind the contact angle later before jet eruption. It agrees generally well (within 20%) with the mathematical analysis. Finally, a droplet impact angle function is proposed for the global LDI erosion prediction.

    A numerical study on turbulence attenuation model for liquid droplet impingement erosion

    Annals of Nuclear Energy, vol. 38, no. 6, pp. 1279-1287

    2011

    DOI: 10.1016/j.anucene.2011.02.010

    Abstract anzeigen

    The bent pipe wall thinning has been often found at the elbow of the drain line and the high-pressure secondary feed-water bent pipe in the nuclear reactors. The liquid droplet impingement (LDI) erosion could be regarded to be one of the major causes and is a significant issue of the thermal hydraulics and structural integrity in aging and life extension for nuclear power plants safety. In this paper two-phase numerical simulations are conducted for standard elbow geometry, typically the pipe diameter is 170 mm. The turbulence attenuation in vapor-droplets flow is analysed by a damping function on the energy spectrum basis of single phase flow. Considering the vapor turbulent kinetic energy attenuation due to the involved droplets, a computational fluid dynamic (CFD) tool has been adopted by using two-way vapor-droplet coupled system. This computational fluid model is built up by incompressible Reynolds Averaged Navier–Stoke equations using standard k–ε model and the SIMPLE algorithm, and the numerical droplet model adopts the Lagrangian approach, a general LDI erosion prediction procedure for bent pipe geometry has been performed to supplement the CFD code. The liquid droplets diameter, velocity, volume concentration are evaluated for the effects of carrier turbulence attenuation. The result shows that carrier turbulence kinetic energy attenuation is proved to be an important effect for LDI erosion rate when investigating the bent pipe wall thinning phenomena.

    Interaction of FKBP5 gene variants and adverse life events in predicting depression onset: Results from a 10-year prospective community study

    American Journal of Psychiatry, vol. 168, no. 10, pp. 1107-1116

    2011

    DOI: 10.1176/appi.ajp.2011.10111577

    Abstract anzeigen

    Objective: The binding protein FKBP5 is an important modulator of the function of the glucocorticoid receptor, the main receptor of the stress hormone system. This turns the FKBP5 gene into a key candidate for gene-environment interactions, which are considered critical for pathogenesis of stress-related disorders. The authors explored gene-environment interactions between FKBP5 gene variants and adverse life events in predicting the first occurrence of a major depressive episode. Method: The analyses were based on 884 Caucasians in a 10-year prospective community study. At baseline, they were 14–24 years old and did not fulfill criteria for a major depressive episode. The DSM-IV-based Munich Composite International Diagnostic Interview was used to assess adverse life events preceding baseline and major depressive episodes during follow-up. On the basis of previous findings, five single-nucleotide polymorphisms (SNPs) within the FKBP5 gene were selected for genotyping. Results: While the authors did not observe genetic main effects, they found interactions between the five SNPs and traumatic (but not separation) events, with the strongest effect for severe trauma. The effect of trauma on incident major depressive episodes was evident among subjects homozygous for the minor alleles but not subjects with other genotypes. The findings were replicated in the U.K. Environmental Risk Longitudinal Twin Study. Conclusions: These hypothesis-driven results suggest that an interaction between FKBP5 genotype and trauma is involved in the onset of depression. Subjects homozygous for the minor alleles of the investigated FKBP5 SNPs seem to be particularly sensitive to effects of trauma exposure in terms of triggering depression onset.

    Klinischen Gesten der Anerkennung. Über die Unvermeidbarkeit eines moralischen Anspruchs

    Zeitschrift für medizinische Ethik, vol. 57, no. 2, pp. 147-155

    2011

    Abstract anzeigen

    Er ist gebildet, seine Haut bleich, seine Hände unruhig. Höflich und aufmerksam kümmert er sich um seine Nachbarn. Bisweilen redet er ekstatisch; ein Schwarzseher, der den Glauben an das Gute verloren hat. Der Zufall bringt Dr. Ragin eines Tages wieder auf die Krankenstation Nr. 6. Als Gromow die Anwesenheit des Arztes bemerkt, entlädt sich sein Zorn: Warum müsse hier ein geringer Teil der Verrückten eingesperrt herumlungern und die Anderen, die Mehrheit könnten ohne Aufhebens ungeniert herumlaufen? Dr. Ragin sieht keinen Grund zu widersprechen: »Daß ich ein Arzt bin und Sie ein Geisteskranker, hat nichts mit Moral und nichts mit Logik zu tun, das ist eine reine Sache des Zufalls«. Trotz des ruppigen Verlaufs der ersten Begegnung zwischen Dr. Ragin und Gromow bemerkt der Arzt, dass auch in der Aggressivität des Disputs eine grundlegend würdigende Anerkennung zum Ausdruck gekommen war; eine Haltung des Respekts, sich mit der Meinung des Anderen ernsthaft auseinanderzusetzen: »In der ganzen Zeit, solange ich hier lebe, ist das, scheint mir, der erste, mit dem man reden kann.«
