Ballistic and dissipative electron transport through a two-dimensional geometry is studied in the de Broglie-Bohm quantal trajectory model. The dissipative effect, incorporated to simulate inelastic scattering, is introduced via an imaginary potentia

We have performed low-temperature conductance measurements on a quantum dot. For zero magnetic field we find transmission resonances in the regions between successive ballistic quantized conductance plateaus. The results of the conductance measuremen

The conductance of large circular quantum dots in high-mobility semiconductor materials displays oscillations as a function of both magnetic field and size. A simple tunneling model has been introduced recently for the interpretation of a particular

Using a mode-matching method, we investigate the ballistic transport properties of noninteracting electrons in two types of semiconductor nanostructures in which the confining potential has smooth, rounded corners. The rounded corners are simulated b

Treatment of patients with implant-supported mandibular fixed prostheses performed according to an early loading concept has shown excellent results in several reports. The outcome of such treatments with 4 implants, in which the posteriors are dista
