A Novel Model for (percolating) Nanonet Chemical Sensors for Microarray-based E-Nose Applications
Our numerical simulations for percolating multi-nanowire (NW) chemical sensors demonstrate the fundamental role of potential barriers at NW-to-NW junctions in dictating sensor response and how the sensor response changes with NW density. Based on this model, we explain the counterintuitive enhancement of detection limit at a high-density NW network sensor.
