Determine type of semiconductor from IV measurements of Schottky

Click For Summary
SUMMARY

Determining the type of semiconductor (n-type or p-type) in a Schottky diode using only I-V measurements is insufficient. A detailed model of the diode is necessary to identify specific quantities related to the substrate type. Additionally, incorporating time-dependent measurements may provide further insights beyond static I-V data. Reference materials, such as the Wikipedia page on P-N diodes, can enhance understanding of the underlying principles.

PREREQUISITES
  • Understanding of Schottky diodes and their characteristics
  • Familiarity with I-V measurement techniques
  • Knowledge of semiconductor physics, particularly n-type and p-type materials
  • Ability to analyze time-dependent electrical measurements
NEXT STEPS
  • Research detailed models of Schottky diodes for better analysis
  • Explore time-dependent measurement techniques in semiconductor testing
  • Study the principles of P-N junctions and their relevance to Schottky diodes
  • Investigate advanced I-V characterization methods for semiconductor materials
USEFUL FOR

Electrical engineers, semiconductor physicists, and researchers involved in diode characterization and semiconductor material analysis.

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?
 
Physics news on Phys.org
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.
