Yellow tungsten oxide nanowires have excellent gas sensitivity so that they are often used to prepare gas sensor. According to the experts, yellow tungsten oxide nanowires and silicon nanowires can be combined to obtain silicon nanowires – tungsten oxide nanowires composite structure, whose interface forms a homogeneous heterojunction. In NO2 gas, the increase of the width of the depletion layer in the heterojunction has an important effect on the improvement of its gas sensing performance.
