Performance optimization of transparent and conductive Zn1-xAlxO thin films for opto-electronic devices: An experimental & first-principles investigation

Abstract In the present work, a combination of the experimental techniques with first principle density functional theory (DFT) based calculations has been employed to study the performance of the aluminum doped ZnO (AZO) thin films as transparent conducting oxide (TCO) material. The AZO thin films with varying doping concentration (0 wt% to 10 wt%) and having thickness (
