Al-p-Si-Al structures were fabricated and temperature dependent capacitance versus voltage measurements were performed in this study. The Al contacts were grown by the sputtering method and then capacitance-voltage characteristics of the devices were performed with forward and reverse biases. According to this measurements, the C-2 –V plots were conducted. With the help of those calculation, the barrier height vs temperature (ΦCV – T), the carrier concentration vs temperature (NA – T) and the depletion width vs temperature (w – T) graphs were plotted. In conclusion, it has been seen that the ΦCV and w decreased, and NA almost remained constant with increasing temperature.

Al-p-Si-Al structures were
fabricated and temperature dependent capacitance versus voltage measurements
were performed in this study. The Al contacts were grown by the sputtering
method and then capacitance-voltage characteristics of the devices were
performed with forward and reverse biases. According to this measurements, the
C^-2 vs V plots were conducted. With the help of those calculation,
the barrier height vs temperature (Φ_CV
vs T), the carrier concentration vs temperature (N_A vs T) and
the depletion width vs temperature (w
vs T) graphs were plotted. In
conclusion, it has been seen that the Φ_CV
and w decreased, and N_A remained constant with
increasing temperature.
