Metal oxides are the most commonly used materials for chemical sensors, originally in the form of thick films. Single-crystalline one-dimensional nanostructures have considerable advantages: high surface-to-volume ratio, readily achieved reduced lateral dimensions, and their high degree of purity and crystallinity. These characteristics permit a variety of gas sensor designs, such as mat-based or single wire devices, self-heating devices, and photoactivation. Despite these advantages, large-scale integration has still not been achieved, and both one- and two-dimensional nanostructures still deserve deep study and research.

Abstract
Metal oxides are the most commonly used materials for chemical sensors, originally in the form of thick films. Single-crystalline one-dimensional nanostructures have considerable advantages: high surface-to-volume ratio, readily achieved reduced lateral dimensions, and their high degree of purity and crystallinity. These characteristics permit a variety of gas sensor designs, such as mat-based or single wire devices, self-heating devices, and photoactivation. Despite these advantages, large-scale integration has still not been achieved, and both one- and two-dimensional nanostructures still deserve deep study and research.File | Dimensione | Formato | |
