Light-matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers have developed a technique that overcomes these limitations.
Researchers have demonstrated a promising asymmetric graphene nanomesh device that shows a high thermal rectification ratio at low temperatures. The experiment provides a practical guideline for developing a high-efficiency thermal rectifier based on graphene nanomesh structure.
Magnets and superconductors don't normally get along, but a new study shows that 'magic-angle' graphene is capable of producing both superconductivity and ferromagnetism, which could be useful in quantum computing.
