Quantum States of Confined Carriers in Very ThinAlxGa1−xAs-GaAs-

Abstract

tive of the XPS spectrum and the low-energy region of the APS threshold over which effects due to the core-level width are expected to dominate. This close agreement strongly suggests that identical initial (core) energy states are involved for both XPS and APS in this case. However, as a result of the increasing predominance of finalstate effects on the high-energy side of the APS threshold, there is no obvious correspondence between features in APS and the peak in the XPS core-level density of states from which the "binding energy" is usually determined.

Fermions in the background of mixed vector–scalar–pseudoscalar square potentials

“…The square potentials, wells and barriers, are models widely used in low-dimensional systems such as the quantum dots [24], Dirac fermions in graphene [25], electrons in semiconductor heterostructures [26] and theoretical studies [27,28]. Besides these applications, the well and barrier potentials are extremely examples used as toy-models in textbooks (for example, see [7] ), further increasing its importance in quantum mechanics.…”

Feature Article - Semiconductor Superlattices with Small Band Offsets

“…These subbands are indexed by a quantum number (say, N), starting from that closest to the bottom of the well for conduction electrons, and from the top of the well for the holes. The subbands corresponding to the same quantum number have the same symmetry (parity), and this results in the so-called "Dingle rule" [15] for interband optical transitions (ΔN = 0), which largely determine the optical properties of type-Ι superlattices.…”

Ferromagnetism in Diluted Magnetic Semiconductor (Ga,Mn)As Quantum Wires and Quantum Wells under the Influence of Photo-Excitation and Spin Wave Scattering

“…Experimental observations indicate that a magnetization curve as a function of magnetic field at 5 K and room temperature ferromagnetic transition temperature are obtained for QWRs [22]. QWs, on the other hand, have been utilized in electronic devices through band gap engineering since their realization [23] and are an interesting subject of study currently. In this paper, the magnetic aspect of these systems are theoretically investigated by analytical method.…”
