Abstract
Neuron-like mechanisms under DC bias are observed in two-port VO2 pads. We investigate these self-oscillations responses for different types of VO2 and uncovered an underlying story common to all materials on how self-oscillations arise. From the electronic responses measured as a function of temperature and time, we determined three precise conditions inducing self-oscillations and very large current spikes. Rather than being caused by an electronic capacitance as previously understood, we prove that such self-oscillations are caused by thermodynamic interactions entirely predicted by material constants. These calculations should extend to other materials, enabling the design of various low-power thermoelectronic computing circuits.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
