Abstract

We have studied the interface formed between a p-type conducting
polyaniline layer and an n-type porous silicon wafer, The contact has
rectifying behaviour demonstrated clearly by the IV curves, We can fit
our data to a simple Schottky barrier model. The barrier height
determined from our data varies from 0.78 to 0.85eV. The ideality
factor ranges from 2.8 - 5.2. Visible electroluminescence has been
obtained from this junction when it is placed under a forward bias.
