High dielectric strength insulator

Click For Summary
SUMMARY

The discussion focuses on identifying insulators with high dielectric strength at room temperature, specifically for applications requiring thin layers around 30 nm. Polysulfide sealants are suggested as a potential material. Additionally, the use of e-beam evaporation and atomic layer deposition techniques is emphasized for the deposition process. The importance of conducting experiments under oil to eliminate moisture is also highlighted.

PREREQUISITES
  • Understanding of dielectric strength and its significance in materials science.
  • Familiarity with e-beam evaporation techniques for thin film deposition.
  • Knowledge of atomic layer deposition (ALD) processes.
  • Basic principles of material properties under varying environmental conditions.
NEXT STEPS
  • Research the properties and applications of Polysulfide sealants in electrical insulation.
  • Explore the principles and advantages of e-beam evaporation for thin film applications.
  • Investigate atomic layer deposition (ALD) techniques and their suitability for high dielectric strength materials.
  • Study the effects of moisture on dielectric materials and methods to mitigate these effects.
USEFUL FOR

Materials scientists, electrical engineers, and researchers focused on developing high-performance insulators for electronic applications.

Hi,

Does anyone know which insulator will have very high dielectric strength at room temperature?

The dielectric strength is the electric filed strength of a material can resist before it breakdown.
 
Engineering news on Phys.org
Have a look at Polysulfide sealants.
 
Or run your experiment under oil (heated first to remove water)
 
Hi, thank you very much for your reply. i am looking for some material can be deposited using ebeam evaporation or atomic layer deposition, since very thin layer (~30 nm) is needed.
