英文摘要	Since interface superconductivity was discovered at the interface between two insulating layers LaAlO3 and SrTiO3, such interface-induced superconducting systems have been a research hotspot in superconductivity. Here, we report homogeneous interfaces formed by stacking chemically exfoliated monolayer TaS2 nanosheets randomly. Enhanced superconductivity of T-c = 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 gamma of restacked TaS2 nanosheets compared to parent 2H-TaS2 crystals. 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.; National key research and development program [2016YFB0901600]; Chinese Academy of Sciences [XDB04040200]; National Science Foundation of China [61376056, 51672301]; CAS Center for Excellence in Superconducting Electronics, Science and Technology Commission of Shanghai [16JC1401700, 14520722000]; SCI(E); ARTICLE; 13; 4623-4626; 139
