Ultrathin amorphous carbon nitride (aCN) films are synthesized on silicon (Si) using a two-step chemical vapour deposition process, achieving uniformity, ultralow roughness and strong N–Si bonds. The resulting aCN/Si photodiodes exhibit high rectification, fast responses and broad-spectrum imaging capabilities.
