Oftentimes, advanced microscopy studies that measure the local performance of energy materials are restricted to probing the surface. Yet, it is recognized that critical operational processes occur within these devices. In Nature Communications, Song et al. dig deeper by implementing tomographic atomic force microscopy to study local electrical transport pathways in a thin-film halide perovskite. From this yields a 3D, nanoscale spatial resolution map of the photoactive area, demonstrating how visualizing material interiors expands our understanding of next-generation energy devices.

深入挖掘以深入了解能源材料

通常，测量能量材料局部性能的高级显微镜研究仅限于探测表面。然而，已经认识到关键的操作过程发生在这些设备内。在Nature Communications中，Song等。通过使用层析X射线原子力显微镜来深入研究，以研究薄膜卤化物钙钛矿中的局部电传输途径。由此产生了光敏区域的3D纳米级空间分辨率图，展示了可视化材料内部如何扩展了我们对下一代能源设备的理解。
