Solar energetic particles may cause
dielectric breakdown in lunar regolith in a permanently shadowed region (PSR).
Its dielectric breakdown strength is 3 times higher than in SiC and more than 30 times better than in Si, the carrier mobility is very high for both carrier types and the thermal conductivity is unsurpassed.
«Lab experiments show that
dielectric breakdown is an explosive process on a tiny scale,» said Jordan.
The next step is to search for evidence of
dielectric breakdown in PSRs and determine if it could happen in other areas on the moon.
Illustration showing how solar energetic particles may cause
dielectric breakdown in lunar regolith in a permanently shadowed region (PSR).
Then they estimated the energy that would be deposited over a million years by both meteoroid impacts and
dielectric breakdown driven by solar storms, and found that each process releases enough energy to alter the regolith by a similar amount.
Its wide band gap makes it a good insulator and protects the PEI film from
dielectric breakdown at high temperatures, the reason for failure in other polymer capacitors.

The material that Wang and his team created restores all properties needed for use as a
dielectric in wearable electronics — mechanical strength,
breakdown strength to protect against surges, electrical resistivity, thermal conductivity and
dielectric, or insulating, properties.
