Study and modelling of self-organized nanostructure in Ge-Mn thin film
Abstract
Nowadays self-organized semiconductor nanostructures have motivated many studies due to the presence of inhomogeneities that can improve physical properties (optical, magnetic …). Among all possible systems, Ge-Mn has emerged as a promising candidate for spintronic application since the discovery of Mn-rich self-organised nanocolumns in Ge matrix exhibiting ferromagnetic properties at operating temperature. Nevertheless, many questions related to the structure, composition, morphology or growth mechanism and physical properties of such nanocolumns remains open. In this work, thanks to 3D imaging capability of atom probe tomography a new and more precise characterization of Mn-rich nanocolumns was provided. Various nanocolumn morphologies (discontinuous, Y shape…) have been observed. Mn-rich nanocolumns were identified as metastable phase (in morphology and in composition). Nanocolumns phase evolution to stable spherical clusters induced by thermal treatment is also studied. These observations have been correlated with binary thin film growth simulation obtained by Kinetic Monte Carlo. Although performed on a rigid lattice with no elastic energy, simulations revealed self-organization of nanocolumns. These simulations allow us to understand the influence of growth parameter and nanocolumn formation mechanisms.
