We review the progress in the industrial production of SiC substrates and epitaxial layers for high power semiconductor devices. Optimization of SiC bulk growth by the sublimation method has resulted in the commercial release of 100 mm n -type 4H-SiC

The current status of SiC bulk growth is reviewed, while specific attention is given to the effect of defects in SiC substrates and epitaxial layers on device performance and yield. The progress in SiC wafer quality is reflected in the achievement of

We present a combined experimental and theoretical investigation of the interface between a B2-type FeSi film and Si(111). Using an ultra-thin B2-FeSi film grown on Si(111), the interface is still reached by electrons, so quantitative low-energy elec

The growth of high-purity, semi-insulating (HPSI) 4H-SiC crystals has been achieved using the seeded-sublimation growth technique. These semi-insulating (SI) crystals (2-inch diameter) were produced without the intentional introduction of elemental d

An intrinsic defect (ID) has been identified in as-grown 4H–SiC by electron paramagnetic resonance (EPR). The EPR parameters of an ID measured in our nominally semi-insulating material are similar to the literature data of the EI5 defect produced i

The production of large diameter, high quality SiC substrates is essential to realize the full potential of this important semiconductor material. The current status of SiC bulk sublimation growth for the production of these substrates is reviewed fr

The magnetic properties of ultrathin Co films and Co/Cu heterostructures grown on Cu(111) have been shown to improve when Pb is used as a surfactant: the thickness range of Co films displaying perpendicular magnetic anisotropy is extended and a compl

Recent apparent discrepancies between results from low-energy electron and X-ray diffraction concerning a reduced in-plane lattice parameter of Cu(100) are resolved in favour of an uncontracted surface. We show that neglecting the energy dependence o

Silicon-carbide-based device technology as well as the volume production of nitride-based, high brightness blue and green LEDs fabricated on SiC substrates has made tremendous progress within the last several years. The commercial availability of lar

Though correlations between surface structure and magnetism are evident, surface structure determinations of ultrathin magnetic films in the crystallographic sense are available only for a few cases. We investigate the three examples Ni/Cu(100), Co/C
