“…e-beam evaporation was used to grow MgO dielectric layer on glass substrate [ 173 ] as well as to grow MgO barrier layer for MgO based magnetic tunnel junctions [ 174 ] and multilayer structure [ 175 ]. This method is utilized by our group for growth of MgO thin films on quartz substrate [ 176 ] and Si substrate having thickness 5 and 50 nm [ 177 ]. The films grown on Si substrate are amorphous (5 nm) and crystalline (50 nm), in nature respectively [ 178 ].…”

Magnesium oxide remained interesting from long time for several important phenomena like; defect induced magnetism, spin electron reflectivity, broad laser emission etc. Moreover, nanostructures of this material exhibited suitability for different kinds of applications ranging from wastewater treatment to spintronics depending upon their shape and size. In this way, researchers had grown nanostructures in the form of nanoparticles, thin films, nanotubes, nanowalls, nanobelts. Though nanoparticles and thin films are well known form of nanostructures and wide variety of synthesis approaches are available, however, limited methodology for other nanostructures are available. In order to grow these nanostructures in an optimized way an understanding of these methods is essential. Thus, this review article depicts an overview of various approaches for design of different kinds of nanostructures.

In spite of the increasing interest in and application of ultrathin film oxide oxides in commercial devices, the understanding of the mechanisms that control the growth of these films at the atomic scale remains limited and scarce. Such a limited understanding stems in no minor part from the fact that most of the available modeling methods are unable to access and robustly sample the nanosecond to second time-scales required to simulate both atomic deposition and surface reorganization at ultrathin films. To contribute to this knowledge gap, here we have combined molecular dynamics and adaptive Kinetic Monte Carlo simulation to study the deposition and growth of oxide materials over an extended timescale of up to approximately 0.5 milliseconds. In our pilot studies we have examined the growth of binary oxide thin films on oxide substrates. We have investigated three scenarios (i) the lattice parameter of both the substrate and thin film are identical (ii) the lattice parameter of the thin film is smaller than the substrate and (iii) the lattice parameter is greater than the substrate. Our calculations allow for the diffusion of ions between deposition events and the identification of growth mechanisms in oxide thin films. We make a detailed comparison with previous calculations. Our results are in good agreement with available experimental results and demonstrate important limitations in former calculations, which fail to sample phase space correctly at the temperatures of interest (typically 300K to 1000K) with self-evident limitations for the representative modeling of thin films growth.
