Electrical-Thermal Switching in Carbon-Black–Polymer Composites as a Local Effect
Electrical-Thermal Switching in Carbon-Black–Polymer Composites as a Local Effect
Following the lack of microscopic information about the intriguing well-known electrical-thermal switching mechanism in carbon-black--polymer composites, we applied atomic force microscopy in order to reveal the local nature of the process and correlated it with the characteristics of the widely used commercial switches. We conclude that the switching events take …
