Ultrathin films of alternating oxide layers have been prepared using a 2D sol‐gel process . The individual layers of TiO 2 (lighter) and ZrO 2 (darker) can be seen in the high‐resolution TEM image shown in the Figure. The 2D sol‐gel process allows the thickness of the individual layers—and of the total structure—to be simply and accurately controlled at a sub‐nanometer level.
