| Description |
Topological insulators (TI) are among the newest wonders in condensed matter. In fact, the ongoing research on TI has attracted huge attentionof condensed matter physics community in recent years[1–3]. Particularly, the insulating band gaps in the bulk, but the gap less high conductivityat surface or edge states had been of tremendous interest[2,4–6]. Basically, the spin of the electron gets locked with the momentum through spinorbit interaction [3]. The topological insulators had been the source of new exotic physics, whereby a band insulator exhibits good conductivity duethe topological surface states and the role of the both spin and momentum is found be important[1–6].Interestingly, enough it was soon realized in early days itself that superconducting state can also be envisaged in a topological insulator andvarious proposals were put forward for accommodation of superconductivity in topological insulators[7–11]. Precisely echoing the fact the gap lesssurface/edge conducting states could eventually be the superconducting one as well [7]. Namely to cite a few superconductivity is reported in (Cu/Sr)xBi2Se3[12–15],Tl0.6Bi2Te3[16], NbxBi2Se3[17], and PdxBi2Te3[18] etc.
