HOMEMADE DIODE FOR PHYSICS AND ELECTRONICS LABS
We constructed a simple diode from commercially available compound semiconductors namely n-TiO2 and p-CuI. The diode is a semiconductor p-n junction, the most basic device of all electronics. The entire diode can be made within 10 minutes without any sophisticated instruments. The current-voltage characteristics showed a similar behavior to a regular Si diode. We use a non-linear fitting procedure to analyze the experimental results. The fitting non- linear model used is based on the work of Danielson and Depoy  with slightly fewer parameters. Diode characteristics and rectification properties are discussed and compared with a regular Si diode. "Accurate Method for Forward and Reverse Bias Curve Fitting of TPV I-V Data,” L. R.
