Intercrystals
Recent advancements in material science have led to the discovery of a new class of materials known as intercrystals. Researchers from Rutgers University–New Brunswick have revealed their unique electronic properties, which could influence future technologies. These materials are formed by stacking ultrathin layers of graphene with a slight twist over hexagonal boron nitride, creating moiré patterns that alter electron movement.
What Are Intercrystals?
Intercrystals are materials that exhibit both quasicrystalline and crystalline properties. They possess non-repeating atomic patterns like quasicrystals but maintain symmetries found in conventional crystals. This hybrid nature allows for unique electronic behaviours not typically observed in standard materials.
The Role of Twistronics
Twistronics is a modern technique that manipulates the angles of layered materials. By adjusting these angles, researchers can create moiré patterns that dramatically change the electronic structure. This method was very important in discovering intercrystals, as it allows for control over electronic properties through geometric adjustments rather than chemical alterations.
Unique Electronic Properties
Intercrystals demonstrate varied electronic properties with minor structural changes. This variability can lead to phenomena such as superconductivity and magnetism. Superconductors are particularly valuable as they enable electrical current to flow without resistance, paving the way for efficient electronic applications.
Potential Applications
The discovery of intercrystals could revolutionise electronic components. They may lead to the development of more efficient transistors and sensors, which traditionally require complex material combinations. Intercrystals could form the foundation of future electronic circuits, where atomic-level geometric tuning controls all functions.
Environmental Impact
Intercrystals present a sustainable alternative to conventional electronic materials. They can be produced from abundant and non-toxic elements like carbon, boron, and nitrogen. This quality makes them a more environmentally friendly option compared to rare earth materials commonly used in electronics.
Future Research Directions
The research team is optimistic about the potential of intercrystals. They believe this discovery opens avenues for further exploration of material properties at the atomic level. Future studies may uncover additional applications and enhance our understanding of electronic materials.
Collaboration and Contributions
The study involved contributions from various researchers, including those from the National Institute for Materials Science in Japan. The collaborative effort puts stress on the international interest in advancing material science and technology.
