Creating quantum spin chains through edge reconstruction in pure graphene armchair nanoribbons towards ballistic spin transport
Ning Wu, Bang-Gui Liu
It is well-known that ferromagnetism can be realized along the zigzag graphene nanoribbon edges, but the armchair graphene nanoribbon edges (AGNEs) are nonmagnetic. Here, we achiev…

Giant Rashba spin splitting in strained KTaO3 ultrathin films for circular photogalvanic currents
Ning Wu, Xue-Jing Zhang, Bang-Gui Liu
Strong Rashba effects at surfaces and interfaces have attracted great attention for basic scientific exploration and practical applications. Here, the first-principles investigatio…
