Determine type of semiconductor from IV measurements of Schottky

In summary, IV measurements in Schottky diodes involve plotting the current-voltage curve to determine the relationship between voltage and current flow. Schottky diodes differ from other semiconductors due to their use of a metal-semiconductor junction. The IV measurement can help determine the type of semiconductor used in a Schottky diode by analyzing the current-voltage curve. Factors such as temperature and purity can affect the IV measurement results. The type of semiconductor can be determined by comparing the IV curve with known characteristics of different types of semiconductors.

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?

Look for a detailed model of the diode in order to identify quantities related to the n- or p-type substrat, have a look at the wiki pages http://en.wikipedia.org/wiki/P–n_diode
Probably one has to go beyond I-V measurements and measure also time dependent quantities.
 

Related to Determine type of semiconductor from IV measurements of Schottky

1. What are IV measurements in Schottky diodes?

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.

2. How do Schottky diodes differ from other types of semiconductors?

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.

3. How does the IV measurement help determine the type of semiconductor in a Schottky diode?

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.

4. What factors can affect the IV measurement results in Schottky diodes?

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.

5. How is the type of semiconductor determined from the IV measurement data?

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.
