heterojunction, Gas sensors, polymers, sensing materials
Abstract
For easy and safe life there are many gas detecting devices present in our day to day life. The sensors are the electronic devices that can detect one form of energy and convert that into appropriate signal which is useful to use. There are many types of sensors available in the market. One of the alternatives is, the interface formed by two similar or dissimilar types of the materials which is called as heterojunction. The review focuses on the various types of heterojunction sensors that can detect the stimulus at very low concentrations of gases. All the sensors are characterized by certain standard parameters such as response time, recovery time, sensor stability, durability etc., which are discussed in detail in this review.
