Numerical Simulation of the Conductivity Relaxation in the High Resistivity Semiconductor
Journal Title: Mathematical Modelling and Analysis - Year 2007, Vol 12, Issue 3
Abstract
A theoretical model describing the relaxation of charge carriers in semiconductors of high resistance under the influence of the laser pulses is presented. It is demonstrated that parameters of the trapping states relevant to the processes of the conductivity relaxation can be defined by fitting the experimental data. Time evolution of the conductivity of the [i]GaAs [/i]bulk semiconductor under the influence of nanosecond and picosecond laser pulses is considered. Effect of two laser pulses, when the first one results in population of the trapping state and the second one induces its depopulation, is also considered.

Unsteady Squeezing Flow of a Viscous MHD Fluid Between Parallel Plates, a Solution Using the Homotopy Perturbation Method
The present paper analyses the unsteady 2-dimensional flow of a viscous MHD fluid between two parallel infinite plates. The two infinite plates are considered to be approaching each other symmetrically, causing the squee...
On Solutions of Neumann Boundary Value Problem for the Liénard Type Equation
We provide conditions on the functions [i]f(x) [/i]and [i]g(x)[/i], which ensure the existence of solutions to the Neumann boundary value problem for the equation [i]x''+f(x)[sup][/sup]x[sup]'2[/sup]+g(x)=0.[/i]
Two-Sample Problems in Statistical Data Modelling
A common problem in mathematical statistics is to check whether two samples differ from each other. From modelling point of view it is possible to make a statistical test for the equality of two means or alternatively tw...
