Atomistic modeling of defect diffusion in SiGe
نویسنده
چکیده
We have developed an atomistic model for dopant diffusion in SiGe structures and we have implemented it in the kinetic Monte Carlo process simulator DADOS. The model takes into account (i) composition and stress effects on the diffusivity of interstitials, vacancies and dopants, (ii) SiGe interdiffusion, (iii) dopant segregation and (iv) the modifications of band-gap and charge levels. The model has been tested for B and Sb providing a very good agreement with available experimental data.

In this paper, an atomistic based finite element model is developed to investigate the influence of topological defects on mechanical properties of graphene. The general in-plane stiffness matrix of the hexagonal network structure of graphene is found. Effective elastic modulus of a carbon ring is determined from the equivalence of molecular potential energy related to stretch and angular defor...

We discuss boron diffusion in biaxial tensile strained {001} Si and SiGe layer with kinetic Monte Carlo (KMC) method. We created strain in silicon by adding a germanium mole fraction to the silicon in order to perform a theoretical analysis. The strain energy of the charged defects was calculated from ab-initio calculation whereas the diffusivity of boron was extracted from the Arrhenius formul...

Introduction: SiGe pMOSFETs show considerable improvements in device performance due to the smaller hole effective mass exhibited by Ge.Further improvement in device performance can be obtained by growing pseudomorphically compressively strained SiGe on Si. Despite a lattice mismatch of ~4% between Si and Ge, researchers have been recently able to fabricate ultrathin body and nanowire pMOSFETs ...
