High quality ultrathin MgB2 superconducting films with thickness down to 7.5 nm have been synthesized via hybrid physical-chemical vapor deposition. The films are phase-pure and oxygen-free. The 7.5 nm thin film shows a T-c(0) of 32.8 K and residual resistivity of 120 mu Omega cm, and the 10 nm thin film shows a T-c(0) of 35.5 K and high critical current density J(c) similar to 10(6) A cm(-2) at 20 K.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000272077600015&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, AppliedPhysics, Condensed MatterSCI(E)EI17ARTICLE12null2
