A recent paper published in NANO showed the gas-solid reaction method provides a full coverage of the perovskite film and avoids damage from the organic solvent, which is beneficial for light capture and electrons transportation, resulting in a faster response time and stability for perovskite photodetectors.
Nature has produced exquisite composite materials—wood, bone, teeth, and shells, for example—that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance.
Researchers from North Carolina State University have developed a new technique for directly printing metal circuits, creating flexible, stretchable electronics. The technique can use multiple metals and substrates and is compatible with existing manufacturing systems that employ direct printing technologies.
MXenes, conductive materials widely used in many industries, now have one more promising application: helping lasers fire extremely short femtosecond pulses, which last just millionths of a billionth of a second.
Scientists at Ben-Gurion University of the Negev (BGU) are proposing a new method to obscure an optical chip by bending light around the object. This could be achieved by manipulating waves in the near field region (such as surface plasmons) of a metamaterial surface (a metasurface) on an integrated photonic structure.
Scientists at the Massachusetts Institute of Technology (MIT) are using chalcogenide glasses to produce flexible hybrid electronics (FHE) that can stretch or conform to the shape of an object or structure without damage, and to better integrate two-dimensional (2D) materials with conventional semiconductor circuits.
