Effects of dislocations on transport properties of two dimensional electron gas. II. The quantum regime

Z. Bougrioua, J. Farvacque, D. Ferre

This article deals with the influence of dislocations on the conductivity of two dimensional electron gas measured at helium temperature and at high magnetic field. Two kinds of dislocation substructures have been experimentally studied: they correspond either to a family of parallel dislocation…

Effects of dislocations on transport properties of two dimensional electron gas. I. Transport at zero magnetic field

Z. Bougrioua, J. Farvacque, D. Ferre

This paper presents a theoretical analysis of the scattering potentials associated with dislocations in the case of two dimensional electron gas. It is shown that dislocations act mainly on the free carrier mobility through the potential associated with their linear electric charge and not with…

Extraction method of the base series resistances in bipolar transistor in presence of current crowding

Emmanuel Dubois, P.H. Bricout, E. Robilliart

This paper proposes a new method to determine the base resistance components and the base sheet resistance under forward bias conditions and in the presence of current crowding. Using bipolar transistors with two independent base contacts, the base sheet resistance R<sub>&square; </sub…

Resonant phonons in adsorbates

Leonard Dobrzynski, B. Djafari Rouhani, P. Zieliński, Abdellatif Akjouj, B. Sylla, E. Oumghar

After a brief review on surface phonons, we focus on resonant phonons in adsorbed thin 1ayers. Such resonances may in general be understood within the substrate bulk band as thin layer modes shiften and broaden by the i n t e r a c t i o n w i t h t h e s u b s t r a t e p h o n o n s.

Magnon band structure of periodic composites

Jerome O. Vasseur, L. Dobrzynski, Bahram Djafari-Rouhani, H. Puszkarski

We calculate the spin-wave spectra of two-dimensional composite materials consisting of periodic square arrays of parallel cylinders made of a ferromagnetic material embedded in a ferromagnetic background. Each material is described by its spontaneous magnetization MS and exchange constant A. An…
