Advances in stacked nanowires, from synthesis to integration, have revolutionized the field of nanotechnology, offering unprecedented opportunities for developing high-performance devices and systems. From bottom-up growth methods to innovative assembly and integration strategies, the advancements discussed herein lay the foundation for harnessing the full potential of stacked nanowires in various fields, including electronics, photonics, energy storage, and sensing. Stacked nanowires, with their unique properties and enhanced functionalities, have attracted significant attention in recent years. However, realizing the full potential of stacked nanowires requires advancements in both synthesis techniques and integration strategies. This article presents the latest developments in these areas, highlighting the progress made in synthesizing stacked nanowire structures and integrating them into functional devices [1].

Bottom-up synthesis techniques play a crucial role in creating well-defined and vertically aligned stacked nanowire structures. Researchers have made remarkable strides in developing innovative methods such as vapor-liquid-solid (VLS) growth, chemical vapor deposition (CVD), and molecular beam epitaxy (MBE) for the controlled growth of stacked nanowires. These techniques enable precise control over nanowire diameter, length, composition, and crystal structure, facilitating the fabrication of tailored stacked nanowire architectures [2].

In addition to bottom-up synthesis, templated growth and directed assembly methods have emerged as powerful strategies for fabricating stacked nanowire structures with predefined arrangements and functionalities. Templates, such as nanoporous membranes or pre-patterned substrates, can guide the growth and alignment of nanowires in a controlled manner. By manipulating the template parameters, researchers can achieve specific stacking configurations, including radial, axial, or hierarchical arrangements, opening up new possibilities for tailored device designs [3].

Integrating stacked nanowires into practical device architectures is a critical step towards realizing their potential in various applications. Significant progress has been made in developing techniques for transferring and assembling stacked nanowires onto substrates or device platforms. Transfer printing, nanomanipulation, and self-assembly methods have been explored to achieve precise positioning, alignment, and interconnection of stacked nanowires. These integration strategies enable the fabrication of functional devices such as transistors, sensors, light-emitting diodes (LEDs), and energy storage systems. Hybridization and heterogeneous integration approaches have further expanded the capabilities of stacked nanowires. By combining different nanowire materials or integrating nanowires with other functional components, researchers can leverage the unique properties of stacked nanowires while incorporating additional functionalities. For instance, hybrid nanowire systems comprising semiconducting, metallic, or functional oxide nanowires can enable multifunctional devices with enhanced performance, such as high-speed transistors or integrated photonics [4,].

Advances in stacked nanowire synthesis and integration techniques have been accompanied by developments in characterization methods. Advanced imaging and spectroscopy techniques allow researchers to analyze the structural, electrical, optical, and mechanical properties of stacked nanowire structures at the nanoscale. These characterization tools provide insights into the growth mechanisms, interfaces, and performance limitations of stacked nanowires, facilitating optimization efforts for further enhancing their properties and device performance [5,6,].


The advances in stacked nanowires, from synthesis to integration, open up exciting avenues for future research and applications. Continued efforts are required to refine synthesis techniques, improve scalability, and develop novel integration strategies that enable seamless incorporation of stacked nanowires into large.
