Ottaviani, L. ; Yakimov, E. ; Hidalgo Alcalde, Pedro ; Martinuzzi, S. | Trans Tech Publications Ltd | 2004Hydrogen is known to passivate donor and acceptor levels in SiC bulk, and also at the surface by forming bonds with Si atoms. Introduction of H atoms can then improve the electrical performance of Schottky diodes by reducing the metal-SiC interf[...]texto impreso
This paper presents cathodoluminescence, electrical and structural characteristics of (11-20)-oriented 4H-SiC substrates, aiming at determining properties of some extended defects. As-grown basal plane dislocations with the Burgers vector b = 1/[...]texto impreso
Hidalgo Alcalde, Pedro ; Ottaviani, L. ; Idrissi, H. ; Lancin, M. ; Martinuzzi, S. ; Pichaud, B. | E D P Sciences | 2004-07Silicon Carbide (SiC) is a wide band gap semiconductor, having opto-electronic properties that are suitable for many applications. Some structural defects due to crystal growth and/or doping technologies are commonly present in the substrates of[...]
