The effect of applying a mesh bias during the syntheses of amorphous titanium oxide (a-TiO2) thin films via mist chemical vapor deposition (mist-CVD) was investigated. When a negative bias is applied to the upstream electrode, some of the large mist particles are captured by the mesh electrode, promoting the generation of fine mist particles and in...

In this work, the electronic and magnetic properties of MnxZn1-xO at various manganese (Mn) concentrations were studied using first principle calculation.
