Abstract
  • In this paper, the electrical and structural properties of Ti/Al Ohmic contacts have been investigated comparing AlGaN/GaN heterostructures with different dislocation density. The annealing temperature leading to Ohmic be-haviour is related to the material quality of the substrate. Moreover a different temperature dependence of the spe-cific contact resistance RC has been observed. (literal)
