Topological insulators are exotic field of study because of presence of fully gapped bulk states and gap less surface states protected by Time Reversal Symmetry (TRS). Occurrence of superconductivity in this wonderful system of materials tantalized condense matter field as only handful of materials are found to exhibit topological superconductivity like Cu,Nb,Sr intercalated Bi2Se3;Tl incorporated Bi2Te3; In doped SnTe. The mechanism for occurrence of superconductivity and pairing symmetry is still a topic of debate. Muon spectroscopy in Zero Field and Transverse Field mode can provide the evidence of unconventional superconductivity along with pairing symmetry and London penetration depth. Our Sr0.1Bi2Se3 sample with large volume fraction is ideal for MuSR study to detect the presence of unconventional superconductivity along with pairing symmetry in this class of materials.
