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…
