'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..
