National University of Singapore physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next-generation moiré quantum matter.Moiré patterns are formed when two identical periodic structures are overlaid with a relative twist angle between them or two different periodic structures but overlaid with or without a twist angle.
Dr. Junxiong Hu, the lead author of the research paper, said, “Our technique helps to solve a real-life problem. Many researchers have told me that it usually takes almost one week to make a sample. With our technique, they can not only greatly shorten the fabrication time, but also greatly improve theThe scientists use a “30° rotation technique” at the start to control the alignment of the top hBN and graphene layers.

Researchers discover quantum switch for regulating photosynthesisPhotosynthesis is a crucial process that allows plants to convert carbon dioxide into organic compounds using solar energy. Light-harvesting complex II (LHCII) is a complex of pigment molecules bound to proteins. It switches between two main functions—dissipating harmful excess light energy as heat under high light intensity through nonphotochemical quenching, and transferring absorbed light to the reaction center with almost a unit efficiency under low light.
