Twistronics of 2D materials

Twistronics, a portmanteau of "twist" and "electronics," refers to the manipulation of the relative twist angle between two layers of 2D materials, typically graphene or other 2D crystals like transition metal dichalcogenides (TMDs), to induce novel electronic properties. This burgeoning field has gained immense attention in recent years due to its potential to engineer and control electronic behaviors in ways previously unattainable. The twist angle between the layers plays a pivotal role in determining the electronic properties, creating a unique playground for researchers to explore a wide range of phenomena, including superconductivity, magnetism, and correlated electron states. One of the most striking discoveries in the realm of twistronics is the emergence of superconductivity at magic angles, where the twisted layers exhibit an unexpected alignment leading to the formation of a flat energy band. This discovery, pioneered in bilayer graphene, has sparked a wave of research into understanding and harnessing this phenomenon for practical applications, such as developing more efficient electronic devices and quantum technologies. Twistronics not only offers a new perspective on fundamental physics but also holds great promise for advancing the field of materials science, paving the way for innovative technologies that could revolutionize the landscape of electronic devices in the future. As researchers continue to delve into the intricacies of twistronics, the potential for ground breaking discoveries and technological advancements remains high, making it a captivating and dynamic area of study at the forefront of materials research
