China亿电竞平台 Powder Net News In recent years, two-dimensional materials (also known as the亿电竞 "cousins" of graphene) composed of fourteenth group elements have attracted great attention because of the亿电竞ir unique potential to become topological insulators with practical value.


So far, it is reported that the亿电竞 two-dimensional orbital structure of lead based materials is the亿电竞 largest in the亿电竞 United States due to its orbital structure. This may make it a robust two-dimensional topological insulator, in which the亿电竞 quantum spin Hall effect may even occur at temperatures higher than room temperature.


The亿电竞平台refore, finding a reliable and low-cost method to synthe亿电竞size lead-ene has been considered as an important goal of materials science research.


Now, led by Nagoya University in Japan, researchers have annealed ultra-thin lead films on palladium to form lead alkenes. From this, we can see that the亿电竞 two-dimensional structure of honeycomb materials can be formed by scanning microscope.


Surprisingly, a kind of palladium lead alloy film with bubble structure is formed under the亿电竞 lead ene, which is similar to the亿电竞 "will Fallon" structure (it divides the亿电竞 space into equal volume units, so as to minimize the亿电竞 sum of surface area between the亿电竞m, thus solving the亿电竞 "Kelvin problem"). The亿电竞平台 design inspiration of the亿电竞 National Swimming Center (also known as "Water Cube") for the亿电竞 2008 Beijing Olympic Games comes from the亿电竞 "will Phelan" structure.
