Interfacial Rashba magnetoresistance of two-dimensional electron gas at LaAlO/SrTiO interface
Kulothungasagaran Narayanapillai, Gyungchoon Go, Rajagopalan Ramaswamy +6
We report the angular dependence of magnetoresistance in two-dimensional electron gas at LaAlO/SrTiO interface. We find that this interfacial magnetoresistance exhibits a s…
Tuneable Sieving of Ions Using Graphene Oxide Membranes
J. Abraham, K. S. Vasu, C. D. Williams +10
Graphene oxide membranes show exceptional molecular permeation properties, with a promise for many applications. However, their use in ion sieving and desalination technologies is…
Molecular transport through capillaries made with atomic-scale precision
B. Radha, A. Esfandiar, F. C. Wang +13
Nanometre-scale pores and capillaries have long been studied because of their importance in many natural phenomena and their use in numerous applications. A more recent development…
Extremely large magnetoresistance in few-layer graphene/boron-nitride heterostructures
Kalon Gopinadhan, Young Jun Shin, Rashid Jalil +4
Understanding magnetoresistance, the change in electrical resistance upon an external magnetic field, at the atomic level is of great interest both fundamentally and technologicall…
Current-driven spin orbit field in LaAlO3/SrTiO3 heterostructures
Kulothungasagaran Narayanapillai, Kalon Gopinadhan, Xuepeng Qiu +4
We demonstrate a current tunable Rashba spin orbit interaction in LaAlO3/SrTiO3 (LAO/STO) quasi two dimensional electron gas (2DEG) system. Anisotropic magnetoresistance (AMR) meas…
Giant magnetoresistance in single layer graphene flakes with a gate voltage tunable weak antilocalization
Kalon Gopinadhan, Young Jun Shin, Indra Yudhistira +2
A clear gate voltage tunable weak antilocalization and a giant magnetoresistance of 400 percent are observed at 1.9 K in single layer graphene with an out-of-plane field. A large m…
