| Description |
We report on the rectifying behavior of sol–gel synthesized Al (1 and 3 at%):ZnO/Si (N–n) thin film isotype heterojunctions. The films were dense and uniform over the substrate and show polycrystalline morphology with defined grain boundaries. The current–voltage (I–V) characteristics of the junctions at room temperature and high temperature in air ambient were found to be asymmetric with an increase in rectification ratio (If/Ir) from 1.29 to 3.70 for 1 at and from 0.60 to 2.54 for 3 at% of Al (at a bias voltage of 5V) for increase in temperature upto 150 oC. The I–V characteristics of th ejunctions were explained on the basis of high temperature carrier injection and single carrier dynamics.
