Tip-induced Superconductivity Coexisting with Preserved Topological Properties in Line-nodal Semimetal ZrSiS
Leena Aggarwal, Chandan K. Singh, Mohammad Aslam +6
ZrSiS was recently shown to be a new material with topologically non-trivial band structure which exhibits multiple Dirac nodes and a robust linear band dispersion up to an unusual…
Enhanced zero-bias conductance peak and splitting at mesoscopic interfaces between an -wave superconductor and a 3D Dirac semimetal
Leena Aggarwal, Sirshendu Gayen, Shekhar Das +3
Mesoscopic point contacts between elemental metals and the topological 3D Dirac semimetal CdAs have been recently shown to be superconducting with unconventional pairing wh…
Comment on "Tip induced unconventional superconductivity on Weyl semimetal TaAs" [arXiv:1607.00513]
Sirshendu Gayen, Leena Aggarwal, Goutam Sheet
Recently, Wang have reported the observation of "unconventional superconductivity" in the Weyl semimetal TaAs [arXiv:1607.00513]. The authors have written "\textit{A con…
Mesoscopic superconductivity and high spin polarization coexisting at metallic point contacts on the Weyl semimetal TaAs
Leena Aggarwal, Sirshendu Gayen, Shekhar Das +5
A Weyl semimetal is a topologically non-trivial phase of matter that hosts mass-less Weyl fermions, the particles that remained elusive for more than 80 years since their theoretic…
Unexpected superconductivity at nanoscale junctions made on the topological crystalline insulator PbSnTe
Shekhar Das, Leena Aggarwal, Subhajit Roychowdhury +4
Discovery of exotic phases of matter from the topologically non-trivial systems not only makes the research on topological materials more interesting but also enriches our understa…
Unconventional Superconductivity at Mesoscopic Point-contacts on the 3-Dimensional Dirac Semi-metal CdAs
Leena Aggarwal, Abhishek Gaurav, Gohil S. Thakur +3
Since the three dimensional (3D) Dirac semi-metal CdAs exists close to topological phase boundaries, in principle it should be possible to drive it into exotic new phases,…
Direct evidence of strong local ferroelectric ordering in a thermoelectric semiconductor
Leena Aggarwal, Jagmeet S. Sekhon, Satya N. Guin +5
It is thought that the proposed new family of multi-functional materials namely the ferroelectric thermoelectrics may exhibit enhanced functionalities due to the coupling of the th…
Observation of hysteretic phase-switching in silicon by piezoresponse force microscopy
Jagmeet S. Sekhon, Leena Aggarwal, Goutam Sheet
We report the observation of phase switching on silicon wafers by piezo-response force microscopy (PFM). The switching is hysteretic and shows remarkable similarities with…
