As in graphene, the layered structures of MoS2 and other transition metal dichalcogenides exhibit electronic and optical properties that can differ from those in bulk. Bulk MoS2 has an indirect band gap of 1.2 eV, while MoS2 monolayers have a direct ...…
The limit of the resolution of an optical microscope is about half of the visible wavelength, called the Abbe limit, which prevents us from understanding the microscopic world more deeply.…
A laser beam (yellow) reflects off a 2D material (orange) highlighting a grain boundary defect in the atomic lattice. To further shrink electronic devices and to lower energy consumption, the semiconductor industry is interested in using 2-…
Scanning transmission electron micrscopy image of superlattice consisting of an alternating sequence of 5 atomic unit cells of neodymium nickelate (blue) and 5 atomic unit cells of samarium nickelate (yellow). The discovery of an unpreceden…
Graphene enhanced heat pipes can efficiently cool power electronics. Credit: Ya Liu/Johan Liu/Chalmers University of Technology Researchers at Chalmers University of Technology, Sweden, have found that graphene-based heat pipes can help sol…
This image shows cartoons and micrographics that highlight the new technique of in situ twistronics. Credit: Artem Mishchenko/The University of Manchester A group of international researchers at The University of Manchester have revealed a…
The world's thinnest and most transparent potential sensor sheet. Transparent electronics—such as head-up displays that allow pilots to read flight data while keeping their eyes ahead of them—improve safety and allow users to access dat…
It is often quoted that the processor is the brain of the computer. But a processor works fundamentally differently from a human brain. Transistors use electronic signals to perform logical operations. Instead, the brain works with nerve cel…
Silica aerogel is a lightweight nanoporous amorphous solid material with excellent thermal and thermal insulation properties.…
A schematic illustration of the synthesis of Graphite. Without transition metal catalysts, CO2 is directly converted into Graphite without the graphitization of amorphous carbon at high temperatures. The variation of sample temperatures and gas press...…
