The electronic and thermal properties of defects introduced during electron beam deposition (EBD) and isochronal annealing of titanium (Ti) contacts on epitaxial p-Si were investigated. In this work, Ti Schottky contacts were annealed with in a temperature range of 50 °C-400 °C. Current-voltage (I-V) measurements were conducted to monitor the change in electrical characteristics with every annealing step. A barrier height of 0.57 eV was measured on the as-deposited sample. Deep level transient spectroscopy (DLTS) and Laplace-DLTS techniques were employed to identify the defects induced after electron beam deposition (EBD) and isochronal annealing of the Ti Schottky contacts. The defect level identified on the as-deposited sample was a hole trap at 0.35 eV, known as the K-centre.
