Abstract

Ni/Al/Ti ohmic contacts with preserved form factor during alloying at 1000 °C, almost constant specific resistance value in the low 10-4 Ohmxcm2 decade, and a very weak temperature dependence in the range 25 - 290 °C, have been obtained on 1x 1020 cm-3 Al+implanted p-type 4H-SiC of different resistivity in the range 6 x10-2- 1 Ohmxcm2. A qualitative data analysis for understanding the hole transport mechanism through the formed metal/semiconductor interface is also shown.
