Ultrahigh‐density data storage is realized using a thermochemical hole‐burning technique based on scanning tunneling microscopy (STM). The heating effect induced by the STM current gives rise to localized thermochemical decomposition of an organic charge‐transfer complex substrate and subsequent gasification of its low‐ boiling‐point decomposition products. A large array of nanometer‐sized holes is recorded on the substrate (see Figure).
