Analytic models of heterogenous magnetic fields for liquid metal flow simulations
(2009)
A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

Peg-in-Hole methods, like the Nine Hole Peg-Board Test (NHPT) and the Perdue board are widely employed for the functional assessment and therapy of the upper limbs of people with Multiple Sclerosis (MS). Such passive devices ...
Properties of the ubiquitous p-n junction in semiconductor nanowires
(2008)
The properties of nanowires with built-in p-n junctions such as the energetic position of the one-dimensional sub-bands, charge distributions and band bending in equilibrium are determined by the self-consistent solution ...
Investigation of spin-polarized resonant tunneling through double-barrier magnetic tunnel junctions by self-consistent solution of the Poisson-Schrödinger equations
(2003)
The article discusses the investigation of spin-polarized resonant tunneling through double barrier magnetic tunnel junctions (DBMTJ) by the self-consistent solution of Poissons and Schrödingers equations using transfer ...
Investigation into the charge distribution and barrier profile tailoring in AlGaN/GaN double heterostructures by self-consistent Poisson-Schrödinger calculations and capacitance-voltage profiling
(2002)
The two-dimensional electron gas (2DEG) distribution and conduction-band profile tailoring of the Al xGa 1-xN/GaN/Al yGa 1-yN/GaN double heterostructure (DH) has been studied in detail by self-consistent Poisson-Schrödinger ...
The Pinch-Off Behaviour and Charge Distribution in AlGaN-GaN-AlGaN-GaN Double Heterostructure Field Effect Transistors
(2001)
AlxGa1-xN/GaN/AlyGa1-yN/GaN double heterojunction field effect transistors with bottom AlyGa1-yN barrier widths between 100 and 2000 Å and Al contents of y = 0.15-0.3 were grown by radio-frequency molecular beam epitaxy ...
Current transport in semiconductor nanowires with built-in barriers based on a 1D transfer matrix calculation
(2008)
A one dimensional (1D) transfer matrix calculation of current transport in semiconductor nanowires with built-in barriers is described within the effective mass approximation by taking into account (i) the quantum confinement ...
Synthesis of Tin nitride Sn xN y nanowires by chemical vapour deposition
(2009)
Tin nitride (Sn xN y) nanowires have been grown for the first time by chemical vapour deposition on n-type Si(111) and in particular by nitridation of Sn containing NH 4Cl at 450 °C under a steady flow of NH 3. The Sn xN ...
An inverse method to assign receptances by using classical vibration absorbers
(2009)
The classical mass-spring absorber can be thought of as a very simple structural modification. In this paper the inverse problem of assigning receptances to a dynamic system by using one or more simple mass-spring absorbers ...
Near critical behavior in the two-dimensional spin-gap system SrCu2(BO3)2
(2002)
The temperature dependence of the powdered X-band ESR spectra has been measured in a two-dimensional spin-gap system SrCu2(BO3)2 in the temperature range between 5 and 300 K. The spectra are composed of two overlapping ...
