چکیده
Abstract Printed metal oxide devices have been widely desired in flexible electronic applications to allow direct integration on foils and reduce waste associated costs. Especially, semiconductor made from non-critical raw materials, such as Zn, Sn (and not, for example, In), gained significant interest. Despite considerable progress the field, upscale requirements lab fab scale produce these materials remain a challenge. In this work, we report importance of solution combustion synthesis (SCS) when compared with sol–gel production zinc tin (ZTO) thin films using solvent (1-methoxypropanol) that has lower environmental impact than used toxic 2-methoxyethanol. To assure compatibility low-cost substrates high-throughput printing techniques, low annealing temperature 140 °C was achieved by combining SCS infrared short processing time. These conditions allowed transition spin-coating (lab scale) flexographic (fab at speed 10 m min −1 roll-to-roll pilot line. The ZTO (1:1 Zn:Sn-ratio) diodes show rectification ratio 3 , operation voltage (⩽3 V), promising reproducibility variability. results provide basis further optimisation (device size, encapsulation) meet electronics passive-matrix addressing, energy harvesting rectification.

متن کاملSynthesis and characterization of single-crystalline zinc tin oxide nanowires
Crystalline zinc tin oxide (ZTO; zinc oxide with heavy tin doping of 33 at.%) nanowires were first synthesized using the electrodeposition and heat treatment method based on an anodic aluminum oxide (AAO) membrane, which has an average diameter of about 60 nm. According to the field emission scanning electron microscopy (FE-SEM) results, the synthesized ZTO nanowires are highly ordered and have...

Nanocrystalline SnOx particles (x 0–2) were synthesized using tetramethyltin (Sn(CH3)4) vapor as the particle precursor reactant in hydrogen/oxygen/argon (H2/O2/Ar) flames. The particle composition and morphology were characterized using X-ray diffractometry, transmission electron microscopy, and nitrogen (N2) surface adsorption. By controlling the concentration of oxygen in the reactant gases ...
متن کاملIncomplete elimination of precursor ligands during atomic layer deposition of zinc-oxide, tin-oxide, and zinc-tin-oxide.
For atomic layer deposition (ALD) of doped, ternary, and quaternary materials achieved by combining multiple binary ALD processes, it is often difficult to correlate the material properties and growth characteristics with the process parameters due to a limited understanding of the underlying surface chemistry. In this work, in situ Fourier transform infrared (FTIR) spectroscopy was employed du...
