Devices exploiting negative differential resistance (NDR) are of particular interest for analogue computing applications, including oscillator-based neural networks1. These devices typically exploit the continuous S-shaped current-voltage characteristic produced by materials with a strong temperature dependent electrical conductivity2 but recent studies have also highlighted the existence of a second, discontinuous (snap-back) characteristic that has the potential to provide additional...[Show more]
