Metal oxide nanostructure for sensor applications

Abstract

Over the years, metal oxide semiconductors are widely used in several sensor applications. Crystalline structure of various nanostructure materials is being employed. Various dimensions of the Nano metric scale and their small crystalline size in a sensor performance. These Nano-sensors are widely used because they are eco-friendly, low cost with good stability and with fast response and recovery time. Depending upon the recent development the nanostructure semiconductors metal oxides and the have various sensing properties in gas sensor, humidity sensors also ultraviolet sensor and biosensor. These sensors are based on various metal oxides such as zinc oxide, tin oxide, tungsten oxide, copper oxide etc. and they have various properties correlated with each other such as their size, shape, and their doping mechanism. For fabrication various methods and technique are addressed with their functionality with the sensor.
