As science ventures deeper into the realm of the microscopic, probing, measuring, and even constructing at increasingly smaller scales, it must seek out a means of observing that is suitable to the desired scale and resolution. In the late 17th century, the journey into this realm began with the development of the optical microscope and the resulting observation of single cells and bacteria.[1]...

During the past two decades, there have been tremendous developments in near-field imaging and local probing techniques. Examples are the Scanning Tunneling Microscope (STM), Atomic Force Microscope (AFM), Near-field Scanning Optical Microscope (NSOM), Photon Scanning Tunneling Microscope (PSTM), and Scanning Thermal Microscope (SThM).Results showed that the average reflectance for a dopant con...

From an interplay between simultaneously recorded noncontact atomic force microscopy and scanning tunneling microscopy images and simulations based on density functional theory, we reveal the location of single hydrogen species in the surface and subsurface layers of rutile TiO2. Subsurface hydrogen atoms (H(sub)) are found to reside in a stable interstitial site as subsurface OH groups detecta...
