High dielectric strength insulator

Click For Summary

Discussion Overview

The discussion centers around identifying insulators with high dielectric strength at room temperature, particularly those suitable for thin layer applications using techniques like e-beam evaporation or atomic layer deposition.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about insulators with high dielectric strength at room temperature.
  • Another participant suggests Polysulfide sealants as a potential option.
  • A different participant proposes conducting experiments under oil, provided it is heated to remove water, as a method to enhance dielectric properties.
  • A follow-up response expresses the need for materials that can be deposited in very thin layers (~30 nm) using e-beam evaporation or atomic layer deposition.

Areas of Agreement / Disagreement

Participants present various suggestions and approaches, but there is no consensus on a specific material or method that meets all criteria.

Contextual Notes

The discussion does not clarify the specific dielectric strength values or the suitability of the suggested materials for the intended application.

Who May Find This Useful

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.

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.
