Organic-inorganic metal halide perovskites have emerged as a promising optoelectronic material with exceptional structure and property tunability. This new generation of functional materials possess excellent properties such as large optical absorption, long carrier diffusion length, high carrier mobility, and low-cost solution production process. Fabrication methods based on inkjet printing emerged for patterning such perovskite micro- and nanostructures. However, these patterning techniques for perovskites are still limited to in-plane fabrication and alignment. To overcome this limitation, researchers have developed a method to print perovskite nanostructures in three dimensions.
Researchers used electron microscopy to observe the cause of failure in a widely used 2D material, which could help researchers develop more stable and reliable materials for flexible electronic devices.
Researchers have developed a novel formulation that describes how heat spreads within crystalline materials. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.
Scientists combine data analysis techniques with molecular dynamics simulations to understand the structure of water on material surfaces.
Researchers use models and experiments to guide and harness transition waves in multi-stable mechanical structures.
An international research team has developed a new method of synthesizing miniature light sources. It is based on a special laser which produces millions of nanolasers from a perovskite film in a few minutes.
Cryogenic electron microscopy can in principle make out individual atoms in a molecule, but distinguishing the crisp from the blurry parts of an image can be a challenge. A new mathematical method may help.
