Fig. 2: Two-terminal device.
From: Magnetic tunnel junction based on bilayer LaI2 as perfect spin filter device
a Side and b top views of the two-terminal device with bilayer LaI2 barrier and multilayer graphene electrodes. Red arrows indicate the spin alignment (AP configuration) and grey color marks the electrodes. c Differential charge density in the two-terminal device (without electrodes). Brown, purple, and green spheres represent the C, I, and La atoms, respectively. Orange and cyan isosurfaces represent accumulation and depletion of electrons, respectively (isosurface value = 0.0002 e/Å3).
