Stochastic arithmetic provides confidence intervals for the numerical results and can be implemented in any existing numerical software by redefining types of the variables and overloading the operators on them. Here some properties of stochastic arithmetic are further investigated and applied to the computation of inner products and the solution to linear systems. Several numerical experiments are performed showing the efficiency of the proposed approach.

Research paper thumbnail of A mobility model correction for ‘atomistic’ drift-diffusion simulation

2011 International Conference on Simulation of Semiconductor Processes and Devices, 2011

ABSTRACT A comprehensive statistical investigation of the increase in resistance associated with ... more ABSTRACT A comprehensive statistical investigation of the increase in resistance associated with charge trapping in 'atomistic' simulations is presented considering a wide range of doping densities and mesh spacing for both classical and quantum formalisms. A modified mobility model for the 'atomistic' simulations is proposed to suppress the error related to the fictitious charge trapping.

The high instantaneous neutron flux, high resolution and low background make this facility well suited for high quality neutron cross section measurements. The scientific programme of the nTOF collaboration include the measurements of neutron capture, fission and (n, xn) reaction cross sections for nuclear technology, nuclear
