Fabrication of nanostructure for sensing application

Abstract

A nanostructural film is one of the highly exploiting research areas particularly in applications in sensor, photocatalytic, and solar-cell technologies. We therefore present morphological and nanostructural properties of tungsten oxide (WO3) and aluminum oxide (Al2O3). In addition, we further explore engineered nanostructures which enable controls of optical, electrical, and mechanical properties. These improvements led to practical applications in gas sensors and surface-enhanced Raman.
