  1. Gordon Conference Reports

  2. Topological Insulator (TI) • The first generation: 2D TI: BixSbx (alloy), HgCdTe (QW). 3D TI: Bi2Se3, Bi2Te3, Sb2Te3, (“H- atom”), Sb2Se3 (not TI),… • Tools: APPES, STM, Optical and Transport. • The second generation: topological superconductor: Holysler-based and Pb-based. NJP 12 (2010) 065013

  3. The future directions: TI or related Physics • 1-2) Quantum anomalous Hall effect/ magnetic doped TI (dilute magnet semiconductor). Hall effect -----QHE; Spin Hall effect----QSHE; Anomalous HE-----QAHE? ---(magnetic- TI) such as HgMnTe3 or Bi2FeSe3….. • 3-4) topological superconductor ----------Majorana Fermions Search for Break Time Reversal Symmetry (F)QH SC Chiral SC; (SrRmO4) Doped TI with Cu Prox. TI near SC Engineer system (not TI based) QSH Topological SC

  4. The future directions: TI or related Physics Doped TI with Cu Prox. TI near SC Engineer system (not TI based) Sau etc. SC+SOC+FMI Jason Alicea: SOC(semi)+SC InSb(110)+SC QSH Topological SC Phys. Rev. B 81, 125318 (2010) and Physics 3, 24 (2010)

  5. The future directions: TI or related Physics • 5-6) TI with strong interaction fTI / tMI Na2TrO3 Bilayer graphene---inter TI “dynamical”-----S.O.C (Sun Kai) tMI

  6. Other stuffs • Band gag of TI：0.4eV • “Spin-plasmonical mode”---Ragbu Sriviv • Proposal Ji Moore: R1: R2:----Magnetic doped TI R3:----SC QH (3-4) polarized Regbu. S. Can be done in Purdue
