AlN thin films were grown at a temperature of 720 °C on (1 1 1) silicon carbide buffer layer deposited in turn on (1 1 1) silicon substrate by introducing Ge at the SiC/Si interface. The growth method used is the solid source molecular beam epitaxy

The effect of the germanium coverage prior to the epitaxial growth of 5 μm thick 3C-SiC on Si(100) substrates were evaluated with Atomic Force Microscopy and μ -Raman spectroscopy. The 3C-SiC layers were grown by atmospheric pressure chemical vapor

The phonon dynamics of wurtzite aluminum nitride contaminated by oxygen were investigated by employing the Raman back scattering, the Fourier Transform Infrared (FT-IR) reflectivity and absorption, and the Brillouin scattering techniques on unseeded

Heteroepitaxially grown 3C-SiC and 2H-AlN layers on Ge modified Si(111) substrates were investigated by Fourier transform infrared spectroscopic ellipsometry. The obtained phonon frequencies increase with increasing Ge pre-deposition indicating a dec

SIMS and transmission electron microscopy studies revealed an improvement of the SiC/Si(100) heterostructure properties if isovalent atoms with larger atomic dimensions than Si and C were used to modify the interface. The Ge incorporation at the inte

In the present study cubic 3C-(Si 1-x C 1-y )Ge x+y solid solutions were created by using ion beam synthesis. 3C-SiC thin layers grown on on-axis Si (111) substrates by Molecular Beam Epitaxy were implanted with Ge in order to incorporate Ge atoms in

An alternative method for stress relaxation in the SiC/Si heteroepitaxial system based on the incorporation of a group-IV element (germanium) into the interface between SiC and Si is presented. We have investigated the effect of the temperature durin

An alternative route to improve the epitaxial growth of 3C-SiC (100) on Si(100) was developed. It consists in covering the silicon wafers with germanium prior to the carbonization step of the silicon substrate. Transmission electron microscopy and μ
