Fig. 5: Light-guided trajectory.

a Schematic of directron trajectory steered by a straight light-guided channel and (b) displacement of directrons in the x-axis and y-axis. c–f Diverse light-guided trajectories of directrons at U = 16 V and f = 30 Hz, with the color bar representing the velocity of directrons. Scale bars, 200 µm. n0 denotes the alignment direction, and E indicates the electric field perpendicular to the xy plane. g 3D simulation of a photoconductive cell in which a light pattern (purple) is projected onto a BSO surface. h xy plot at z = 5 μm of the simulated electric potential distribution driven by U = 16 V. The axis dimensions in (g) and (h) are in micrometers.
