Physics of GaAs/AlAs Superlattices

Nanophysics in graphene: neutrino physics in quantum rings and superlattices.

Electrons in graphene at low energy obey a two-dimensional Dirac equation, closely analogous to that of neutrinos. As a result, quantum mechanical effects when the system is confined or subjected to potentials at the nanoscale may be quite different from what happens in conventional electronic systems. In this article, we review recent progress on two systems where this is indeed the case: quan...

The Effect of Teaching History of Physics on Student-Teachers’ Understanding of the Process of Model Construction in Physics

To improve student teachers’ understanding of the process of model construction in Physics, it was hypothesized that teaching the history of Physics may be of help. To test this hypothesis, two groups of senior year female student-teachers in Teaching of Physics at one of the campuses of Farhangian University in Tehran were chosen: One group had passed a course on the history of Physics, while ...

Spinodal Superlattices of Topological Insulators

Spinodal decomposition is proposed for stabilizing self-assembled interfaces between topological insulators (TIs) by combining layers of iso-structural and iso-valent TlBiX2 (X = S, Se, Te) materials. The composition range for gapless states is addressed concurrently to the study of thermodynamically driven boundaries. By tailoring composition, the TlBiS2−TlBiTe2 system might produce both spino...

Magnetism of LaAlO3/SrTiO3 superlattices

Magnetic superlattices and multilayers

We brie#y review the active areas of current research in magnetic superlattices, emphasizing later years. With recent widening use of advanced technologies, more emphasis has been made on quantitative atomic level chemical and structural characterization. Examples where the multilayer structure has been controlled, characterized and correlated with the physical properties are discussed. The phy...
