Induced Changes

A systematic investigation has been made on surface defect states of crystallites in the crystallization process of sputtered amorphous silicon films by isothermal annealing. Transmission electron microscopic observations indicate a pronounced vertical columnar structure in the upper part of the films, where the crystallization is delayed. Admittance spectroscopy reveals that two newly generated energy levels with the crystallization are attributed to the crystallites in the lower and upper parts of the films in view of the anisotropic crystallization. These thermally induced changes can be well explained by Si–Si shearing modes at the interfaces of crystallites through the process of crystallization.

In this paper we report a wave-function visualization of the core-induced interaction of a non-hydrogenic Rydberg atom in an electric field and its resultant redistribution of the spectral line intensities. The energy levels and oscillator strengths are calculated based on an effective potential where the radial part of the wavefunction is expanded in a B-spline basis. The calculation is in good agreement with the experimental measurements of the absorption spectrum of sodium atoms in an electric field of F = 840 V/cm, both below and above the saddle point Esp. The visualization of the wavefunction for the eigenstates can help us to see how they stem from the interaction between two or more red and blue hydrogenic states. An approximate localized symmetry close to the atomic core is also observed in the wavefunctions, which accounts for the alternation of oscillator strengths in the experiment.

Constant External Magnetic Field

The oscillator strength for magneto-optical transitions in the far-infrared spectral region is investigated considering one-electron states in a semiconductor quantum-ring (QR) nanostructure subjected to a constant external magnetic field. We analytically solve the stationary Schrödinger equation by applying hard-wall confinement conditions to a model system of the QR using the cylindrical geometry. The energy levels of this model system are calculated after solving the secular equation in a way that is independent of the particular material involved. The approach permits us to obtain universal results in the above sense. Dipole-allowed magneto-optical transitions are studied by calculating their oscillator-strength. We also analyze the persistent current due to the magnetic flux threaded by the QR. The results obtained are discussed in detail and comparison with previous works on this subject are made.
