Transparent conductive thin films for flexible electronics

            Transparent conductive oxides (TCOs) are class of materials which combines high optical transmittance
above 80% in the visible spectrum with resistivity below 10-3 Ωcm.
Nowadays, Sn-doped indium oxide (ITO) and Al-doped zinc oxide (AZO) thin films are the most used TCOs,
which are widely applied as transparent electrodes for various flat panel displays such as liquid crystal displays,
plasma displays and organic light emitting diodes and for thin film solar cells.
The AZO films are considered as a cheap and non-toxic alternative to ITO,
but it is more difficult to achieve similar values of resitivity.

            Fabrication of inorganic TCO on polymer substrates has been of increasing interest due
to their potential applications such as touch screen displays or piezoelectric energy harvester.
Nevertheless, the brittleness of inorganic thin films often results in a failure of the flexible electronic
devices due to strains formed during stretching, folding or bending.
Moreover, the polymer substrates are often temperature-sensitive.
The investigation of TCOs thin films with suitable properties
deposited at low temperatures is of great importance in the field of flexible electronics.
