Abstract
Two semiconducting metal oxide (SMO) sensors are proposed for ppb detection of ammonia (NH3) in applications such as environmental monitoring and health related issues. One sensor uses a gold doped glancing angle deposition(GLAD) tungsten trioxide (WO3) nanorod film and the other uses a standard flat gold (Au) doped film. The GLAD film sensor showed a faster response than the flat film sensor indicating that metal oxide films with nanorod structures have applicability for ppb gas sensing applications.
