Abstract
The study focuses on utilization of block copolymer (BCPs) as template for selective infiltration of AZO precursors. BCPs consist of chemically distinct polymer blocks that are self-assembled into well-defined domains with different morphologies. Vapor phase infiltration (VPI) provides a controlled approach for synthesizing fingerprint-patterned AZO nanowires, offering advantages in terms of conformal coating, vertical alignment, precursor control, scalability, and compatibility with atomic layer deposition (ALD) platforms making it suitable for different applications. The aim of this research is to fabricate nanostructured materials with controlled compositions and patterns which have applications in optoelectronic, sensing, surface engineering, and high-resolution imaging systems. The self-assembled structure of AZO nanowires resemble human fingerprints and exhibits a unique combination of intricate patterns, replication accuracy, large-scale reproducibility, enhanced surface area, and tailored optoelectronic properties. BCP and self-assembly allows for the accurate replication of the fingerprint pattern onto the nanowire arrays. The results demonstrate successful replication of fingerprint patterns of the AZO nanowires. Hence, based on these performance characteristics, this developed approach of fingerprint-patterned AZO nanowires represents a significant advancement in technology and hold potential for revolutionizing various fields, from security systems to sensor technologies, driving innovation in the realm of nanotechnology.
