Extended Data Fig. 4: Static and dynamic spatiotemporal photocurrent profiles of the four devices.
From: Monolithic silicon for high spatiotemporal translational photostimulation

a, Two static heat maps demonstrating the photocurrent distribution of Por-Si on horizontal and vertical planes. b, Spatiotemporal photocurrent heat maps of monolithic Por-Si reveal bipolarity evolution and ___domain boundary diffusion during charge (light on) and discharge (light off) when illumination is directed to the device bottom-left corner. The photocurrent normalization methods are different for the static and dynamic profiles (see Methods).
