Faithful modeling of transient processes in two-dimensional compact open resonance structures

Using a two-dimensional ensemble Monte Carlo (EMC) method, the steady and transient properties of side-gated nanotransistors with single gate and double gate are studied in detail. Simulation results show that the double-gated nanotransistor has more powerful controlling ability on the channel than the single-gated one. The transient processes of the drain current for the two devices are both about 3 ps, which imply that the working speed of the two devices may reach about 0.3 THz. The detail of transient processes for the double-gated nanotransistor is trivial. But for the single-gated nanotransistor, the drain current response shows obviously oscillating during approaching the next steady state. The phenomenon of drain current oscillations is also discussed.

Made In

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Definition Of

1. The definition of “normal” stars in spectral classification changes with time; at the time of the publication of theYerkes Spectral Atlasthe term “normal” was applied to stars whose spectra could be fitted smoothly into a two-dimensional array. Thus, at that time, weak-lined spectra (RR Lyrae and HD 140283) would have been considered peculiar. At the present time we would tend to classify such spectra as “normal”—in a more complicated classification scheme which would have a parameter varying with metallic-line intensity within a specific spectral subdivision.

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.
