Graphene 'cousin' lead latest olefine topological insulators was expected to become practical1

Graphene from graphite materials as a stripping out of 2 d carbon materials, has showed its excellent thermal effect, electrical properties and low temperature hydrogen absorption, normal temperature without scattering, strain sensing, and other functions. And with the rapid iteration of synthetic technology of materials science, graphene & other; Friends and relatives & throughout; They also started to go people line of sight, lead is one such example. Ene is because of its unique structure, lead to the nanometer nature adds a beautiful beautiful scenery, but the future lead ene in the application of touch screen, electronic products, such as the super capacitor will gradually become a reality.

according to science daily website reported recently in the United States, the family of 14 elements of two-dimensional material ( Graphene & other; Cousin & throughout; ） Attracted much attention in recent years, because they have potential to become topological insulators. Recently, Japanese scientists for the first time, let the pure theoretical lead base of two-dimensional cellular materials lead ene ( plumbene) Become a reality.

lead ene compelling reason: lead the electron orbital structure and creating the largest band gap, make it have the greatest spin orbit interaction, this is likely to make it become a kind of robust two-dimensional topological insulators. In this kind of insulator, quantum spin hall effect might even under the environment of higher than room temperature. Therefore, to find a reliable and cheap method of synthesis of lead has been an important objective of materials science research.

in the latest study, a team of researchers led by Nagoya university, through the thin lead on palladium membrane annealing treatment, produced the lead, the resulting surface material with two-dimensional monolayer of iconic cellular structure.

to their surprise, under the lead material formed a palladium lead alloy thin film with bubble structure, similar to & other; Will & ndash; Phelan & throughout; Structure ( It equal dividing the space into a volume unit, let them contact surface area between the sum of the minimum) 。 In 2008, Beijing national swimming center and other Olympic venues; Water cube & throughout; Design inspiration comes from & other; Will & ndash; Phelan & throughout; Structure.

the team leader pomelo chun said, Beijing & other; Water cube & throughout; And & other Will & ndash; Phelan & throughout; Structure is not architects and materials scientists first example inspired each other. He said: & other; In 1967, the architect buck Westminster & middot; Fuller designed the geodesic line at the Montreal world's fair in his name was named & lsquo; Buck Westminster & middot; Fullerene & rsquo; 。 We can look forward to, the 2020 Tokyo Olympic Games, the 2024 Olympics in Paris, dubai world expo in 2020, the world expo 2023 in Buenos Aires, and other activities of 2025 world expo in Osaka venues are likely to show the future of new materials and cause attention. ”
