We demonstrate atomically resolved amplitude modulation ultrahigh vacuum dynamic force microscopy at room temperature. A feasible time response was obtained with 1.8MHz second resonance frequency of a commercially available silicon cantilever while keeping a high mechanical quality factor. Enhanced detection sensitivity due to small amplitude, high mechanical quality factor, and high resonance frequency enabled imaging of the Si(111)-7×7 surface at the attractive region. Three kinds of atomic contrast were obtained with same imaging parameters. Towards fast imaging, a constant amplitude shift image of 128×128pixels with atomic resolution was obtained within 4.75s.
