Is There a UV Lamp that Can Generate 150 nm Light for Bandgap Measurement?

Click For Summary
SUMMARY

The discussion centers on the need for a UV lamp capable of generating light down to 150 nm for optical characterization of wide bandgap semiconductors, specifically those with a bandgap of approximately 6.2 eV. Users are seeking alternatives to synchrotron sources, and the Heraeus Noblelight vacuum UV lamps are highlighted as a viable option, with some models capable of emitting light as low as 112 nm. This information is crucial for researchers focused on bandgap measurement as a function of temperature.

PREREQUISITES
  • Understanding of wide bandgap semiconductors
  • Knowledge of optical characterization techniques
  • Familiarity with UV light sources and their applications
  • Basic principles of bandgap measurement
NEXT STEPS
  • Research the specifications of Heraeus Noblelight vacuum UV lamps
  • Explore optical characterization methods for wide bandgap semiconductors
  • Investigate alternative UV light sources for bandgap measurement
  • Learn about the effects of temperature on semiconductor bandgap
USEFUL FOR

This discussion is beneficial for researchers, materials scientists, and engineers involved in semiconductor characterization and those specifically working with wide bandgap materials.

Is there a UV lamp (not a synchrotron) that will generate UV light down to say 150 nm? I need a light source to do optical characterization (bandgap measurement as a function of temperature) of a wide bandgap semiconductor (~6.2 eV), so I would prefer a light source below 200 nm, ideally around 150 nm. Is there such a thing?

Thanks.

Some models go down to 112 nm.

Thanks a lot.
