Ant clustering algorithms are a robust and flexible tool for clustering data that have produced some promising results. This paper introduces two improvements that can be incorporated into any ant clustering algorithm: kernel function similarity weig

Using complementary surface analysis techniques, we study the Ge growth on distinct SiC(0 0 0 1) reconstructions and elucidate complex mechanisms occurring by thermal activation. Two Si-rich reconstructions, (3 × 3) and , and one C-rich, , are conce

The Ge growth behaviour on the 3x3 Si-rich surface termination of 4H-SiC(0001) has been investigated in this study. After the deposit of one Ge monolayer at room temperature by molecular beam epitaxy, the film is submitted to isochronal annealing cyc

Reflection high-energy electron diffraction (RHEED) has been used to determine epitaxy relationships and in-plane orientations between Ge and SiC(0 0 0 1). Three monolayers of Ge have been deposited at 500 °C on a graphitized SiC (6√3 × 6√3)R30

Epitaxial Ge islands on a SiC(0 0 0 1) substrate have been examined by reflection high-energy electron diffraction (RHEED). These islands have been obtained by depositing three monolayers of Ge at 500 °C on a graphitized SiC (6√3×6√3)R30° reco

The initial Ge growth stages on a (√3 × √3)R30°-reconstructed SiC(0 0 0 1) surface (√3) have been studied using a complete set of surface techniques such as reflection high energy electron diffraction (RHEED), low energy electron diffraction

The Ge growth on SiC(0 0 0 1) follows a Stranski–Krastanov mode for Si-rich (3×3) and ( 3 × 3 )R30° reconstructed surfaces. For Ge deposit in particular temperature conditions, a new (4×4) superstructure takes place and the reflection high ener

By using reflection high energy electron diffraction (RHEED), atomic force microscopy (AFM), high-resolution transmission electron microscopy (HRTEM) analyses, we show that the well-known Stranski–Krastanov growth mode of Ge/Si(0 0 1) can be modifi

The Si capping of small Ge dots nucleated on a C-precovered Si(001) surface has been investigated by means of reflection high-energy electron diffraction and atomic force microscopy. The growth at 500 °C of three Ge monolayers on the C-induced c(4×

With the aim of comparing initial Ge adsorption and desorption modes on different surface terminations of 4H–SiC(0 0 0 1) faces, 3 × 3, √3×√3R30° (R3) and 6√3×6√3R30° (6R3) reconstructions, of decreasing Si surface richness, have been
