Proximity-effect-induced Superconducting Gap in Topological Surface States – A Point Contact Spectroscopy Study of NbSe₂/Bi₂Se₃ Superconductor-Topological Insulator Heterostructures

Journal Article Dai, Wenqing ; Richardella, Anthony ; Du, Renzhong ; ... - Scientific Reports

Proximity-effect-induced superconductivity was studied in epitaxial topological insulator Bi₂Se₃ thin films grown on superconducting NbSe₂ single crystals. A point contact spectroscopy (PCS) method was used at low temperatures down to 40 mK. An induced superconducting gap in Bi₂Se₃ was observed in the spectra, which decreased with increasing Bi₂Se₃ layer thickness, consistent with the proximity effect in the bulk states of Bi₂Se₃ induced by NbSe₂. At very low temperatures, an extra point contact feature which may correspond to a second energy gap appeared in the spectrum. For a 16 quintuple layer Bi₂Se₃ on NbSe₂ sample, the bulk state gap value nearmore »« less

Proximity-induced superconductivity in a topological crystalline insulator

Journal Article Rachmilowitz, Bryan ; Zhao, He ; Li, Hong ; ... - Physical Review B

Superconducting topological crystalline insulators (TCIs) are anticipated to host new topological phases protected by crystalline symmetries, but available materials are insufficiently suitable for surface studies. To induce superconductivity at the surface of a prototypical TCI SnTe, we use molecular beam epitaxy to grow a heterostructure of SnTe and a high-T_c superconductor Fe(Te,Se), utilizing a “buffer” layer to bridge the large lattice mismatch between SnTe and Fe(Te,Se). Using low-temperature scanning tunneling microscopy and spectroscopy, we measure a prominent spectral gap on the surface of SnTe, and demonstrate its superconducting origin by its dependence on temperature and magnetic field.

Two-stage proximity-induced gap opening in topological-insulator–insulating-ferromagnet ${({Bi}_{x} {Sb}_{1 - x})}_{2} {Te}_{3}$ – $EuS$ bilayers

Journal Article Yang, Qi I. ; Kapitulnik, Aharon - Physical Review B

To further investigate the interplay between ferromagnetism and topological insulators, thin films of the low-carrier topological insulator (Bi_x Sb_{1 - x})₂ Te₃ were deposited on the insulating ferromagnet EuS (100) in situ. AC susceptibility indicates magnetic anomalies between T ≈ 30 K and T ≈ 60 K , well above the Curie temperature T_C ≈ 15 K of EuS. When the Fermi level is close to the Dirac point and the surface state dominates the electric conduction, sharp increases in resistance with decreasing temperatures were observed concurrently with the magnetic anomalies. Positive-negative magnetoresistance crossovers were observed at the Curie temperature,more »« less

Structural and proximity-induced ferromagnetic properties of topological insulator-magnetic insulator heterostructures

Journal Article Jiang, Zilong ; Chang, Cui-Zu ; Tang, Chi ; ... - AIP Advances

The spontaneously broken time reversal symmetry can lead to the formation of an energy gap in the Dirac spectrum of the surface states of a topological insulator (TI) which can consequently give rise to a variety of interesting phenomena potentially useful for spintronics. In this work, we couple a non-magnetic TI to a high Curie temperature T_C magnetic insulator to induce strong exchange interaction via the proximity effect. We have successfully grown 5 quintuple layer thick ternary TI (Bi_xSb_1-x)₂Te₃ films on atomically flat yttrium iron garnet (YIG) film with the combination of molecular beam epitaxy and pulsed laser deposition, inmore »« less

Proximity-Induced Magnetic Order in a Transferred Topological Insulator Thin Film on a Magnetic Insulator

Journal Article Che, Xiaoyu ; Murata, Koichi ; Pan, Lei ; ... - ACS Nano

Breaking the time reversal symmetry (TRS) in a topological insulator (TI) by introducing a magnetic order gives rise to exotic quantum phenomena. One of the promising routes to inducing a magnetic order in a TI is utilizing magnetic proximity effect between a TI and a strong magnetic insulator (MI). Here, we demonstrate a TI/MI heterostructure prepared through transferring a molecular beam epitaxy (MBE)-grown Bi₂Se₃ film onto a yttrium iron garnet (YIG) substrate via wet transfer. The transferred Bi₂Se₃ exhibits excellent quality over a large scale. Moreover, through wet transfer we are able to engineer the interface and perform a comparativemore »« less
