Quantum Transport in a Nanosize Silicon-on-Insulator Metal-Oxide-Semiconductor

An approach is developed for the determination of the current flowing through a nanosize silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFET). The quantum mechanical features of the electron transport are extracted from the numerical solution of the quantum Liouville equation in the Wigner function representation. Accounting for electron scattering due to ionized impurities, acoustic phonons and surface roughness at the Si/SiO2 interface, device characteristics are obtained as a function of a channel length. From the Wigner function distributions, the coexistence of the diffusive and the ballistic transport naturally emerges. It is shown that the scattering mechanisms tend to reduce the ballistic component of the transport. The ballistic component increases with decreasing the channel length.Comment: 21 pages, 8 figures, E-mail addresses: [email protected]

Banking union in historical perspective: the initiative of the European Commission in the 1960s-1970s

This article shows that planning for the organization of EU banking regulation and supervision did not just appear on the agenda in recent years with discussions over the creation of the eurozone banking union. It unveils a hitherto neglected initiative of the European Commission in the 1960s and early 1970s. Drawing on extensive archival work, this article explains that this initiative, however, rested on a number of different assumptions, and emerged in a much different context. It first explains that the Commission's initial project was not crisis-driven; that it articulated the link between monetary integration and banking regulation; and finally that it did not set out to move the supervisory framework to the supranational level, unlike present-day developments

Efficiency Gains of a European Banking Union

An anticipated benefit of the prospective European Banking Union is stronger supervision of European banks. Another benefit would be enhanced resolution of banks in distress. While national governments confine themselves to the domestic effects of a banking failure, a European Resolution Authority would follow a supranational approach, under which domestic and cross-border effects within Europe are incorporated. Using a model of recapitalising banks, this paper develops indicators to measure the efficiency improvement of resolution. Next, these efficiency indicators are applied to the hypothetical resolution of the top 25 European banks, which count for the vast majority of cross-border banking in Europe. Our cost-benefit analysis indicates that the UK, Spain, Sweden, and the Netherlands are the main beneficiaries and thus have the largest economic incentives to join Europe’s Banking Union

Circumstellar molecular line absorption and emission in the optical spectra of post-AGB stars

We present a list of post-AGB stars showing molecular line absorption and emission in the optical spectrum. Two objects show CH+, one in emission and one in absorption, and ten stars show C2 and CN in absorption. The Doppler velocities of the C2 lines and the rotational temperatures indicate that the line forming region is the AGB remnant. An analysis of the post-AGB stars of which CO millimeter data is available suggests that the C2} expansion velocity is of the same order as the CO expansion velocity. HD56126 has been studied in detail and we find a mass-loss rate of Mdot=2.8e-4 Msol/yr, fC2=2.4e-8 and fCN=1.3e-8. The mass loss derived from C2 is significantly larger than Mdot=1.2e-5 Msol/yr derived from CO. We find that all objects with the 21mu feature in emission show C2 and CN absorption, but not all objects with C2 and CN detections show a 21mu feature.Comment: plain latex 8 pages, 4 postscript figures, uses psfig.st
