We report grazing incidence X-ray scattering and high angle X-ray diffraction measurements of the structure of sputtered Cu/Co multilayers. Compared with structures grown by molecular beam epitaxy (MBE) the roughness at the Cu/Co interfaces has little conformality and is almost uncorrelated between the bottom and the top. The lateral correlation length is short in comparison with the MBE materi...

Abstract The reflection high-energy electron diffraction (RHEED) method is widely used for the in situ observation of molecular beam epitaxy (MBE). This because RHEED pattern dynamically changes according to growth conditions, such as surface temperature and material supply. However, date, has been categorized recognized based on experience researcher. In this study, we investigated classificat...

Transmission electron microscopy has been combined with time-resolved reflectivity and ion channeling to study the effects of carbon doping on solid-phase epitaxial regrowth �SPER� of strained 2000 Å, Si0.88Ge0.12Si alloy layers grown by molecular-beam epitaxy �MBE�. Relative to the undoped layers, carbon incorporation in the MBE grown SiGe layers prior to regrowth at moderate temperatures �500...

The numerical simulation of the dynamics of the molecular beam epitaxy (MBE) growth is considered in this article. The governing equation is a nonlinear evolutionary equation that is of linear fourth order derivative term and nonlinear second order derivative term in space. The main purpose of this work is to construct and analyze two linearized finite difference schemes for solving the MBE mod...

Recently, a number of coding techniques have been reported to achieve near toll quality synthesized speech at bit-rates around 4 kb/s. These include variants of Code Excited Linear Prediction (CELP), Sinusoidal Transform Coding (STC) and Multi-Band Excitation (MBE). While CELP has been an effective technique for bit-rates above 6 kb/s, STC, MBE, Waveform Interpolation (WI) and Mixed Excitation ...

We report the growth of ZnSe nanowires and nanoneedles using molecular beam epitaxy (MBE). Different growth regimes were found, depending on growth temperature and the Zn–Se flux ratio. By employing a combined MBE growth of nanowires and nanoneedles without any postprocessing of the sample, we achieved an efficient suppression of stacking fault defects. This is confirmed by transmission electro...

We report the first photoluminescence (PL) characterization of InAs nanowires (NWs). The InAs NWs were grown on GaAs(111) B and Si(111) substrates using the Au-assisted molecular beam epitaxy (MBE) growth technique or metal-organic chemical vapor deposition (MOCVD). We compared the PL response of four samples grown under different conditions using MBE or MOCVD. High-resolution transmission elec...
