Nitrogen doped ZnO (N-ZnO) chemiresistive gas sensor was fabricated to improve lower limit of detection (LLOD). N-ZnO was fabricated by mixing ZnO with urea using ball milling method followed by annealing. Both pure ZnO and N-ZnO possess porous morphology. N-ZnO sensor showed a more improved LLOD (2...
