摘要：

Samarium　hexaboride　(SmB6)　predicted　to　be　a　topological　Kondo　insulator,　is　the　first　strongly　correlated　heavy　fermion　material　to　exhibit　topological　surface　states.　In　this　work,　the　high　quality　SmB6　single　crystal　have　been　successfully　grown　by　the　floating　zone　method　and　the　electrical　transport　at　low　temperature　was　measured　at　Oxford　Instruments　Heliox　VL.　The　results　show　that　the　electrical　resistivity　displays　a　sharp　increase　below　20　K,　which　value　is　about　105　higher　than　that　of　room　temperature.　And　the　Hall　resistivity,　which　is　linear,　yielding　an　n-type　carrier　concentration　as　indicated　(low　T　regime).　©　2014　IEEE.
