Deposited Films

Сopper aluminium oxide (CuAlO2) was successfully prepared within the single-step sparking process at the atmospheric pressure. The as-deposited films were then annealed at 400, 900, 1000, and 1100 ∘C in an oven. The results have shown that the annealing temperature has direct effect on the morphology, phase transformation, and optical properties. CuAlO2 in the delafossite phase was formed on the annealed films at temperatures higher than 900 ∘C. Furthermore, the energy band gaps of the annealed films were linearly increased from 3.3 to 3.8 eV with increasing the annealing temperature from 400 to 1100 ∘C due to a reduction of the oxygen deficit of films at high annealing temperatures.

Nanostructured Oxide

Surface modifications influence material interactions such as wettability, imparting hydrophobicity or hydrophilicity. Mainstream research focused on enhancing product shelf-life, directs attention towards superhydrophobic surfaces (SHS). SHS offer several benefits for outdoor applications such as self-cleaning, anti-soiling, anti-mist etc. In this manuscript, we explore the possibility of combining structural and chemical modifications to metal substrates in order to create superhydrophobic metal oxide surfaces. ZrO2-nanotubes are evaluated with regard to their application as transparent UV-stable superhydrophobic coatings. Nanostructured oxide surfaces are created via single-step electrochemical anodization. The absence of HF acid-based pre-etching steps offer a safe and alternatively a green synthesis route. Anodized oxides are modified using octadecylphosphonic acid self-assembled monolayers, demonstrate superhydrophobicity and are evaluated for their mechanical stability under a jet of water, chemical stability under indirect sunlight irradiation in air/water and direct UV exposure. Zirconia nanotubular films were evaluated for optical transparency using light microscopy and surface wettability of the different zirconia-composites was compared to the model system-titania. Structural and compositional differences of the SAM layer upon time dependent decay were analyzed with X-ray photoelectron spectroscopy. <br>

AbstractTransfer printing of high mobility inorganic nanostructures, using an elastomeric transfer stamp, is a potential route for high-performance printed electronics. Using this method to transfer nanostructures with high yield, uniformity and excellent registration over large area remain a challenge. Herein, we present the ‘direct roll transfer’ as a single-step process, i.e., without using any elastomeric stamp, to print nanoribbons (NRs) on different substrates with excellent registration (retaining spacing, orientation, etc.) and transfer yield (∼95%). The silicon NR based field-effect transistors printed using direct roll transfer consistently show high performance i.e., high on-state current (Ion) >1 mA, high mobility (μeff) >600 cm2/Vs, high on/off ratio (Ion/off) of around 106, and low hysteresis (<0.4 V). The developed versatile and transformative method can also print nanostructures based on other materials such as GaAs and thus could pave the way for direct printing of high-performance electronics on large-area flexible substrates.
