Basic Research Research Excellence Center of the material structure and interaction of the School of Physics、Professor Xu Xiaozhi, a key laboratory in Guangdong Province Professor Xu Xiaozhi, cooperation with Professor Liu Kaihui, Peking University,Making important progress bet365 live online casino in the manufacturing of low -dimensional single crystal materials,Realized the preparation of large -sized single -crystalline diamond noodles stacking double -layer tungsten sulfide (WS2) thin film。The research results are based on the title "Remote Epitaxy of Single-Crystal Rhombohedral WS2 Bilayers",Published on May 16th on "Nature Communications"。

Compared to a single -layer transition metal sulfur ethnic compound,Double -layer materials for diamond surface stacking have better optics、Electrical and Iron Electric Performance,It is the alternative material for the new generation of electronics and optoelectronic bet365 live online casino devices。but,At present, the preparation of single crystal double -layer thin film is facing the following problems: 1. Double -layer nuclear potential barriers are higher; 2. Uniformly uniform film into the film is uncontrollable; 3. Single stacking method is difficult to achieve。Therefore,Single Crystal Dalph Noodles Ducts Double -layer transition metal sulfur ethnic compound preparation has not been realized。

In this job,The research team reported a remote extension manufacturing technology,Realized universal preparation of single crystal dual -layer diamond surface stacking transition metal sulfur film on the sapphire。The principle bet365 live online casino is: 1. Use high W source concentration to reduce the dual -layer nuclear power base,Realize a large -scale dual -layer uniformity; 2. Select the sapphire substrate with weaker interaction,Make sure that the double -layer core grows up at the same time,Realize the preparation of a uniform double -layer WS2 film with high coverage; 3. Use the sapphire surface atomic steps to realize the single diamond surface stacking growth of double WS2,Finally, the preparation of large -sized monocrystalline diamond noodles stacking double -layer WS2 thin film。This research promotes the preparation and application of multi -layer single crystal diamond facial stacking transition metal bet365 casino blackjack sulfur compound thin film。
