| 英文摘要 | Since interface superconductivity was discovered at the interface between two insulating layers LaAlO3and SrTiO3, such interface-induced superconducting systems have been a research hotspot in superconductivity. Here, we report homogeneous interfaces formed by stacking chemically exfoliated monolayer TaS2nanosheets randomly. Enhanced superconductivity of Tc= 3 K is observed, compared with 0.8 K of parent 2H-TaS2. The measurement of heat capacity shows the increase of electronic specific-heat coefficient γ of restacked TaS2nanosheets compared to parent 2H-TaS2crystals. Density functional theory calculations indicate that increase and delocalization of electron states near the Fermi surface due to the homogeneous interfaces effects could account for the enhanced superconductivity. © 2017 American Chemical Society. |
