Optimization of transparent conducting oxide ZnO compound thickness in terms of four alloys thermo-physical performance aggregates

▶ Gathering a low-cost and highly controlled fabricating method. ▶ Giving dually experiment–theory evidence to a conjectured and NEVER demonstrated statement. ▶ Proposing conjoint: thermo-opto-mechanical analyses never gathered as-presented. ZnO is one of the well-known metal oxide semiconductors, which has been found, in the last four decades, to be very useful as transparent conductors and UV detectors in optoelectronic devices. This binary compound that showed quantum confinement effects in accessible size ranges was elaborated using several techniques. In the present work, the sprayed pyrolysis technique was carried out to prepare undoped ZnO crystals with different controlled thicknesses. Particularly, and parallel to recently performed measurements, a recently proposed range of optimal layer thickness d is validated, through original conjoint morphological–structural–physical investigations.
