The superconductivity recently found in the doped topological insulator Cux Bi2 Se3 offers a great
opportunity to search for a topological superconductor. We have successfully prepared a single-crystal
sample with a large shielding fraction and measured the specific-heat anomaly associated with the
superconductivity. The temperature dependence of the specific heat suggests a fully gapped, strongcoupling superconducting state, but the BCS theory is not in full agreement with the data, which hints
at a possible unconventional pairing in Cux Bi2 Se3 . Also, the evaluated effective mass of 2:6me (me is the
free electron mass) points to a large mass enhancement in this material.

In the past two years, the three-dimensional (3D) topological insulator (TI) has been attracting a lot of interest
as a new state of matter [1–3]. It is characterized by
the existence of a gapless surface state that emerges because of the nontrivial Z2 topology of the insulating bulk
PACS numbers: 74.25.Bt, 74.25.Op, 74.62.Dh, 74.70.Ad
the topological surface state may turn into a 2D topological
superconductor as a result of a SC proximity effect [4].
Therefore, it is important to confirm whether the superconductivity is really occurring in the bulk of Cux Bi2 Se3
and, if so, to elucidate the fundamental nature of its
Examples •  Samples 1& 5, clear and complete outlines •  Sample 4, great outline but missing figure plans. •  Sample 2 & 3, great outlines but missing &tle and message sentence. •  Sample 6, not concrete. •  Sample 7, hard to understand Outline <-­‐> Abstract •  Tie each sec&on of outline to the abstract. •  Make sure results are presented in a concrete manner. •  Make sure the ques&on (purpose) and answer are clear. Outline <-­‐> Paragraphs •  Outline bullet point = topic sentence + stress point •  Structure of paragraph: •  Topic sentence •  Suppor&ng material •  Stress sentence Outline <-­‐> Figures and Tables •  Use big fonts for figures labels and legends (24~32 pt) •  Use vector images (pdf or ps) that scales, rather than bitmaps •  Use legends over text cap&on
