Multivalley Superconductivity in Monolayer Transition Metal Dichalcogenides

Abstract: In transition metal dichalcogenides (TMDs), Ising superconductivity with an antisymmetric spin texture on the Fermi surface has attracted wide interest due to the exotic pairing and topological properties. However, it is not clear whether the Q valley with a giant spin splitting is involved in the superconductivity of heavily doped semiconducting 2H-TMDs.Here by taking advantage of a high-quality monolayer WS 2 on hexagonal boron nitride flakes, we report an ionic-gating induced superconducting dome with a rec… Show more

“…Similar to graphene, TMDCs exhibit robust in-plane covalent bonding and weak interlayer van der Waals interactions, thus enabling the efficient exfoliation of the bulk structure [17]. Until now, several 2D TMDCs have been reported as superconductors [18][19][20][21]. Apart from TMDCs, other 2D compounds based on transition metals, namely transition metal-carbides, nitrides, carbochalcogenides, borides, oxides, hydrides, and halides etc.…”

“…Since the 2004 discovery of graphene [1][2][3], due to the numerous intriguing features resulting from the bulk to monolayer transition, two-dimensional (2D) materials [4] have been drawing more and more attention [5]. The layered structure of the transition metal dichalcogenides (TMDC) [6] and their intriguing characteristics [5,6], such as superconductivity [7][8][9], charge density waves [9][10][11], the creation of intercalation compounds [12], etc., have drawn the attention of several researchers [13]. The 2D family's transition-metal dichalcogenides (TMDs) have undergone the most extensive research [4].…”
