Light-enhanced gating effect at the interface of oxide heterostructure
Neha Wadehra, Ruchi Tomar, Yuichi Yokoyama +5
In semiconducting materials, electrostatic gating and light illumination are widely used stimuli to tune the electronic properties of the system. Here, we show a significant enhanc…
Planar Hall Effect and Anisotropic Magnetoresistance in a polar-polar interface of LaVO-KTaO with strong spin-orbit coupling
Neha Wadehra, Ruchi Tomar, R. K Gopal +3
Among the perovskite oxide family, KTaO (KTO) has recently attracted considerable interest as a possible system for the realization of the Rashba effect. In this work, we impro…
Observation of Shubnikov-de Haas Oscillations, Non-trivial Berry Phase, Planar Hall and Anisotropic Magnetoresistance at the conducting interface of EuO-KTaO
Nand Kumar, Neha Wadehra, Ruchi Tomar +3
The momentum dependent splitting of spin-bands in an electronic system is known as the "Rashba effect". Systems with the "Rashba effect" possess a Dirac point in momentum space. An…
Observation of planar Hall effect in Type-II Dirac semimetal PtTe
Amit Vashist, R. K. Singh, Neha Wadehra +2
We report experimental observation of the Planar Hall effect (PHE) in a type-II Dirac semimetal PtTe. This unusual Hall effect is not expected in nonmagnetc materials such as P…
Electrical domain writing and nanoscale potential modulation on LaVO/SrTiO
Mohammad Balal, Shilpa Sanwlani, Neha Wadehra +2
The high-mobility 2DEGs formed at the interfaces between certain insulating perovskite oxides have been known to be a novel playground of exotic physical orders like, superconducti…
