NEGATIVE CAPACITANCE
NOT COVID
Ferroelectric and Ferromagnetic properties of metamaterials appear to play a role in CMNS...
Developing control of such properties (tunable or switchable ferromagnetism) is of interest. Nano tech breakthrough and discovery provides insight.
Negative Capacitance is a new frontier to study as well as discharge triggering and nano emitters. waveguides. Nano energy control or focusing methods in, what may described as, 'Smart CMNS Solid State Systems', are considered possible. Nano and LENR advancements are in lockstep, joined at the hip.
Worth keeping watch of.
Study arenas expand.

- Creating negative capacitance requires careful manipulation of a material property called ferroelectricity, which occurs when a material exhibits a spontaneous electrical field. Previously, the effect has only been achieved in ferroelectric materials called perovskites, whose crystal structure is not compatible with silicon.

- by combining hafnium oxide and zirconium oxide in an engineered crystal structure called a superlattice, which leads to simultaneous ferroelectricity and antiferroelectricity.
- “We found that this combination actually gives us an even better negative capacitance effect, which shows that this negative capacitance phenomena is a lot broader than originally thought,” said study co-first author Suraj Cheema, a postdoctoral researcher at UC Berkeley. “Negative capacitance doesn’t just occur in the conventional picture of a ferroelectric with a dielectric, which is what’s been studied over the past decade. You can actually make the effect even stronger by engineering these crystal structures to exploit antiferroelectricity in tandem with ferroelectricity.”
