The development of periodic nanostructures is crucial for advancements in material science and nanotechnology. Traditional fabrication methods frequently encounter issues with complexity and scalability. However, combining bottom-up self-assembly of block molecules with top-down lithography presents an effective solution, facilitating the creation of intricate nanostructures.
Addressing these challenges requires innovative fabrication techniques. This review explores these challenges by harnessing the unique properties of block molecules, which can self-assemble into intricate two-dimensional (2D) patterns. This approach promises significant progress in nanofabrication, with potential applications spanning various technological fields.
The review delves into the self-assembly of block molecules, which results in the formation of various two-dimensional (2D) periodic nanopatterns, including tetragonal, hexagonal, rectangular, and oblique structures. The researchers outline the progression from simple columnar phases to intricate 2D tiling morphologies in materials such as block copolymers, liquid crystals, and giant molecules. They achieve sophisticated nanostructures with specific functionalities by integrating directed self-assembly with top-down lithography.
The study emphasizes advanced nanofabrication techniques that facilitate the creation of complex and functional nanostructures. Highlighting the need for greater complexity in block molecules and enhanced lithography methods, the researchers propose a pathway to low-dimensional ordered morphologies. This innovative approach has the potential to transform nanotechnology by enabling the fabrication of more complex and functional structures than traditional methods.
Our findings demonstrate the immense potential of block molecules in creating complex nanostructures. By integrating self-assembly with advanced nanofabrication techniques, we can pave the way for new applications in nanotechnology, overcoming the limitations of traditional methods.
