In this article, we demonstrate physical reservoir computing (RC) in ovonic threshold switching (OTS) devices. We show that SiGeAsSe OTS is suitable as a physical reservoir because of the nonlinear change in the number of delocalized defects. With the combination of phase space reconstruction (PSR), our algorithm can project data into high-dimensional spaces, thereby enhancing the distinguishabili...Show More
Any product that stops functioning before its declared useful lifetime will be deemed substandard at best, dangerous or fatal at worst. Integrated circuits (ICs) are typically a part of a larger product, which, depending on the target market, may be expected to operate reliably for up to multiple decades, often in extreme environments, and in mission-critical applications. It is therefore essentia...Show More
Total-ionizing-dose (TID) effects are evaluated in top-gated IGZO thin-film transistors (TFTs) irradiated with different gate biases. Negative-bias irradiation leads to worst case degradation of TID response, primarily due to enhanced charge trapping in the SiO2 insulator that underlies the IGZO channel and serves as an oxygen-penetration layer during device processing. TID response comparisons wi...Show More
