I was wondering if it would be possible to determine if a Schottky diode was n-type of p-type (in the bulk) by only using I-V measurements?
IV measurements refer to the measurement of current (I) and voltage (V) characteristics in a Schottky diode. This involves plotting the current-voltage curve, which shows the relationship between the applied voltage and the resulting current flow in the diode.
Schottky diodes are different from other types of semiconductors because they use a metal-semiconductor junction instead of a p-n junction. This makes them faster and more efficient, but also limits their use to applications that require high frequency or high-speed switching.
The IV measurement can provide information about the electrical characteristics of the semiconductor material used in the Schottky diode. By analyzing the shape and behavior of the current-voltage curve, scientists can determine if the semiconductor is a metal, a p-type or n-type material, and if it has any impurities or defects.
The IV measurement results in Schottky diodes can be affected by various factors such as temperature, applied voltage, and the quality and purity of the semiconductor material. Additionally, any damage or imperfections in the metal-semiconductor junction can also impact the results.
The type of semiconductor in a Schottky diode is typically determined by comparing the measured IV curve with known characteristics of different types of semiconductors. This can be done by analyzing the shape, threshold voltage, and other features of the curve to identify the type of material used in the diode.
