Fig. 5: Control of the electron beams in a multi-channel device.
From: Magnetic electron collimation in three-dimensional semi-metals
a False-color electron micrograph of a Cd3As2 (purple) multi-channel device. The scale bar is 10 μm in width. The colored solid lines are a schematic illustration of the electron beams when the magnetic field is along the different angles shown by the dashed lines in (b). The current is sourced between the contacts a and b, and all pairs of bottom voltages are measured. The arrow points to the position when the magnetic field is at 17° as shown in the simulation of (a).
