Strong Superconducting Proximity Effect in Pb-Bi2Te3 Hybrid Structures
To study the interface between a conventional superconductor and a topological insulator, we fabricated Pb-Bi(2)Te(3)-Pb lateral and sandwiched junctions, and performed electron transport measurements down to low temperatures. The results show that there is a strong superconducting proximity effect between Bi(2)Te(3) and Pb, as that a supercurrent can be established along the thickness directio...
متن کاملGeometric dependence of Nb-Bi2Te3-Nb topological Josephson junction transport parameters
Superconductor-topological insulator–superconductor Josephson junctions have been fabricated in order to study the width dependence of the critical current, normal state resistance and flux periodicity of the critical current modulation in an external field. Previous literature reports suggest anomalous scaling in topological junctions due to the presence of Majorana bound states. However, for ...
متن کاملMicrostructural study of Ti/3YSZ interface in NI 105/Ni/Nb/Ti/3YSZ diffusion bonding
In this research, the diffusion bonding of the stabilized zirconia ceramic and Nimonic 105 superalloy using Ti/Nb/Ni multi-interlayer was carried out. Joint was performed using the plasma spark technique in a vacuum atmosphere and at different temperatures and times. The microstructure of the different joint zones was studied using optical and FESEM microscopes equipped with an EDS analyzer. Th...

متن کاملDemonstration of surface transport in a hybrid Bi2Se3/Bi2Te3 heterostructure
In spite of much work on topological insulators (TIs), systematic experiments for TI/TI heterostructures remain absent. We grow a high quality heterostructure containing single quintuple layer (QL) of Bi2Se3 on 19 QLs of Bi2Te3 and compare its transport properties with 20 QLs Bi2Se3 and 20 QLs Bi2Te3. All three films are grown on insulating sapphire (0001) substrates by molecular beam epitaxy (...
