Van der Waals surface reconstruction of mica enables large-scale, unidirectional epitaxial growth of two-dimensional metal oxides (M = Co, Fe, Ni, Mn) into single-crystalline films.
- Why it matters: Hybrid integration of two-dimensional metal oxides with silicon is central to the More-than-Moore roadmap, but making single-crystalline films has been difficult.
- What they did: The authors reconstruct mica’s oxygen atomic plane and use quantum-mechanics calculations to identify it as critical, then grow centimetre-scale Fe-doped CoO films.
- The result: The Fe-doped CoO films show room-temperature ferromagnetic semiconductor properties with a Curie temperature up to 430 K, supporting exploration for quantum physics and spintronics devices.
