Surface graphitization of 4H/6H SiC previously flattened by hydrogen etching was analyzed in UHV by LEED and AES, and in aient air by AFM. Mobility of graphite films grown on the C-face of 4H-SiC ranges from 1000 to 10,000 cm$^{2}$/Vs. Magnetotransport of the graphite film shows 2D gas behavior, accompanying with SdH oscillations and Hall

Basic Parameters of Silicon Carbide (SiC)

Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).Other polylypes with rhornbohedral unit cell: 21R-SiC 24R-SiC, 27R-SiC etc.

Interface trap properties of thermally oxidized n-type …

This work presents detailed investigations of interface traps at the Si-face 4H- and 6H-SiC/SiO 2 interfaces using thermally stimulated current (TSC) and capacitance-voltage ( C- V) techniques. Using n-type material we focus on the interface traps near the SiC conduction band edge which, in the case of 4H-SiC, severely suppress the effective mobility in n-channel metal-oxide-silicon carbide

Interface properties of metal‐oxide‐semiconductor

04/06/1998· This work reports on the interface properties of metal‐oxide‐semiconductor (MOS) structures formed by thermal oxidation of n‐type silicon carbide (SiC). The SiC layers, grown homoepitaxially on the silicon‐face of 6H‐SiC and 4H‐SiC substrates, were oxidized at 1100 °C in dry or wet atmosphere. The interface properties of the MOS structures were investigated using both, the …

01/03/2000· The impact of technology is reflected in the description of the simulated structures. SiC devices must be realized by using chemical vapor deposition (CVD), heteroepitaxy 3C–SiC on Si substrates in the case of 3C–SiC devices, homoepitaxy by the step-controlled epitaxy method in the case of 6H–SiC and 4H–SiC devices, reactive ion etching (RIE), and relatively shallow ion implantations.
