Parallel-leaky capacitance equivalent circuit model for MgO magnetic tunnel junctions
Ajeesh M. Sahadevan, Kalon Gopinadhan, Charanjit S. Bhatia +1
The capacitance of MgO based magnetic tunnel junctions (MTJs) has been observed to be magnetic field dependent. We propose an equivalent circuit for the MTJs with a parallel-leaky…
Universal scaling of resistivity in bilayer graphene
Kalon Gopinadhan, Young Jun Shin, Hyunsoo Yang
We report the temperature dependent electrical transport properties of gated bilayer graphene devices. We see a clear evidence of insulating behavior due to electron-hole charge pu…
Magnetism in MoS2 induced by MeV proton irradiation
S. Mathew, K. Gopinadhan, T. K. Chan +9
Molybdenum disulphide, a diamagnetic layered dichalcogenide solid, is found to show magnetic ordering at room temperature when exposed to a 2 MeV proton beam. The temperature depen…
Strong electronic correlation and strain effects at the interfaces between polar and nonpolar complex oxides
A. Annadi, A. Putra, Z. Q. Liu +6
The interface between the polar LaAlO and nonpolar SrTiO layers has been shown to exhibit various electronic and magnetic phases such as two dimensional electron gas, super…
Atomically flat interface between a single-terminated LaAlO3 substrate and SrTiO3 thin film is insulating
Z. Q. Liu, Z. Huang, W. M. Lü +5
The surface termination of (100)-oriented LaAlO3 (LAO) single crystals was examined by atomic force microscopy and optimized to produce a single-terminated atomically flat surface…
