Graphical Abstract

Figure 3b–d presents the corresponding cross-sectional STEM images of trenches, where the silicon dioxide is visualized as the dark layer. The shape of trenches was mainly determined by the

In contrast, the deeper trenches presented in Figure 3c,d cut through the SiO2 layer, and their bottom is located in the crystalline silicon substrate. The small bright regions near the bottom of the trenches correspond to the implanted
