Directional Activated Exciton Highway via Fractal Electric Field Modulation for Ultrasensitive Carbon Nanotube-Based Sensors

“…In particular, the number of CNTs in unit area and the contact morphology of CNTs play a critical role in improving the device sensitivity and signal stability in the application of practical carbon-based devices such as a vapor sensor . However, among the reported CNT electrochemical sensors, less attention has been paid on enhancing the effective ratio of activated sites with a directional-aligned CNT network. , The random direction distribution of CNTs lead to the existence of too many inactive pathways and inactive sites, which greatly limit the device performance. Under such circumstances, the growth-aligned modulation of CNT devices offer an opportunity to eliminate complexity from inter-CNT interactions, simplifying the chemical sensing mechanisms and precluding sensor drift or degradation .…”
