Modern microelectronics and micromachining are based on crystalline silicon. The increasing demand for sensors able to operate in harsh environment, as temperature above 300 °C, high pressures, intense vibrations or corrosive liquids, has stimulated

In this work, ohmic contacts, formed by 100nm Ni layer RTA annealed or not, were investigated on 3C-SiC epilayers exhibiting different nitrogen doping levels. The epilayers were grown on (100) silicon. Doping level (N) and eventual dopant contaminati

We have investigated the influence of several growth parameters on the incorporation of doping species in the case of 3C-SiC layers grown by CVD on silicon. This includes nitrogen (both intentional and residual) as well as residual aluminum. All conc

Due to the large differences in lattice parameters and thermal expansion coefficients, the heteroepitaxial growth of 3C-SiC on Si mainly results in highly defective layers on strongly bent wafers. The defects may not be detrimental for very basic app

We present a comparative study of C-terminated and Si-rich 3C-SiC(100) surfaces exposed to a H 2 /CH 4 microwave plasma used in diamond growth. Each surface is characterized before and after short plasma exposures using LEED, XPS and STM techniques.

The fabrication process and the spectral properties of gratings for the infrared wavelength region on the basis of 3C-SiC layers grown by CVD on (100) oriented Si substrates are demonstrated. The formed 3C-SiC gratings on Si support two phonon polari

An extended set of vicinal surfaces has been prepared in a 6H-SiC(0001) substrate by mechanically grinding a concaveshaped surface, followed by hot hydrogen etching. During grinding, the different crystallographic planes building up the 6H-SiC polyty

A concave-shaped surface has been prepared in a 6H–SiC(0 0 0 1) substrate by mechanical grinding. As a consequence, the different crystallographic planes building up the 6H–SiC polytype are cut under continuously changing polar angles in all azim
