'Electret' - that was the word - but yep, something a bit different here..
albeit still amenable to calorimetry i should think.
"Quote: A subthreshold swing is demonstrated below the thermal limit in an
electrochemical cell that mimics a gate-to-channel circuit cell in a FeFET,
surpassing the limit imposed by dissipation energy, often designated as
“Boltzmann tyranny.”"
..implying that the energy distribution of the source electrons is somewhat
passive, lacking the high-energy tail / hot electron leakage limiting FET
efficiency, ie. more circumvention than violation..
