In physics, the moiré pattern is a specific geometrical design in which sets of straight or curved lines are superposed on top of each other. Recent studies have found that bilayers of transition metal dichalcogenide materials ...
A research team led by Professor Jyh-Ming Wu of the Department of Materials Science and Engineering at National Tsing Hua University (NTHU) in Taiwan has recently developed two composite piezoelectric materials extracted ...
When two similar atomic layers with mismatching lattice constants—the constant distance between a layer's unit cells—and/or orientation are stacked together, the resulting bilayer can exhibit a moiré pattern and form a moiré ...
A new study recently published in Advanced Materials reveals that MoSe2, a prominent material of the transition metal dichalcogenides (TMDs) family, loses relative stiffness when its thickness is reduced. This work was carried ...
In 1884, Edwin Abbott wrote the novel Flatland: A Romance in Many Dimensions as a satire of Victorian hierarchy. He imagined a world that existed only in two dimensions, where the beings are 2D geometric figures. The physics ...
Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure ...
A McGill research team has developed a new technique to detect nano-sized imperfections in materials. They believe this discovery will lead to improvements in the optical detectors used in a wide range of technologies, from ...
Measurements of the optical response of 2-D transition-metal dichalcogenides have now pinpointed real material systems in which a hypothesized light-squeezing quasiparticle can form. The 2-D exciton-polariton, which couples ...
H2O2 is an important commodity chemical and potential energy carrier, and is widely used for various environmental, medical and household applications. At present, about 99% of H2O2 is produced from an energy-intensive anthraquinone ...
Since the development of diffractive optical elements in the 1970s, researchers have increasingly uncovered sophisticated fundamental principles of optics to replace the existing bulky optical elements with thin and lightweight ...
