New Theoretical Approach to Quantum Size Effects of Interactive Electron-hole in Spherical Semiconductor Quantum Dots
Baptiste Billaud, Marco Picco, T. T. Truong
The issue of quantum size effects of interactive electron-hole systems in spherical semiconductor quantum dots is put to question. A sharper theoretical approach is suggested based…
Physics of Silicene Stripes
A. Kara, C. Leandri, M. E. Davila +5
Silicene, a monolayer of silicon atoms tightly packed into a two-dimensional honeycomb lattice, is the challenging hypothetical reflection in the silicon realm of graphene, a one-a…
Field-Driven Domain-Wall Dynamics in GaMnAs Films with Perpendicular Anisotropy
Alexandre Dourlat, Vincent Jeudy, Aristide Lemaître +1
We combine magneto-optical imaging and a magnetic field pulse technique to study domain wall dynamics in a ferromagnetic (Ga,Mn)As layer with perpendicular easy axis. Contrary to u…
Electronic transport in AlMn(Si) and AlCuFe quasicrystals: Break-down of the semiclassical model
G. Trambly de Laissardière, J. P. Julien, D. Mayou
The semi-classical Bloch-Boltzmann theory is at the heart of our understanding of conduction in solids, ranging from metals to semi-conductors. Physical systems that are beyond the…
Critical behavior of magnetic thin films as a function of thickness
X. T. Pham Phu, V. Thanh Ngo, H. T. Diep
We study the critical behavior of magnetic thin films as a function of the film thickness. We use the ferromagnetic Ising model with the high-resolution multiple histogram Monte Ca…
Effect of transition-metal elements on the electronic properties of quasicrystals and complex aluminides
Guy Trambly De Laissardière, Didier Mayou
In this paper, we briefly present our work on the role of transition-metal element in electronic structure and transport properties of quasicrystals and related complex phases. Sev…
