We report a universal transfer methodology for producing artificial heterostructures of large-area freestanding single-crystalline WTe2 membranes on diverse target substrates.The transferred WTe2 membranes exhibit a nondestructive structure with a carrier mobility comparable to that of as-grown films(~179–1055 cm2·V?1·s?1).Furthermore,the transferred membranes show distinct Shubnikov–de Haas quantum oscillations as well as weak localization/weak anti-localization.These results provide a new approach to the development of atom manufacturing and devices based on atomic-level,large-area topological quantum films. 相似文献
