Hopping-Transport Mechanism for Reconfigurable Logic in Disordered Dopant Networks
Open accessAbstract
The rise of artificial intelligence has led to an explosion in demand for computing power---demand that soon will be insatiable using conventional CMOS-based computing hardware. Thus there is a worldwide quest for unconventional hardware that can replace or complement CMOS-based gear. This study contributes to that quest simulations of how reconfigurable logic can be realized in disordered dopant networks in a semiconductor. This paper reveals the operating principles, based on variable-range hopping of charges between randomly located dopants, that underlie the performance of complex classification tasks by these networks.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
