We report a new tip for scanning tunneling microscopy and a tip repair procedure that allows one to reproducibly obtain atomic images of highly oriented pyrolytic graphite with previously inoperable tips. The tips are shown to be relatively oxide-free and highly resistant to oxidation. The tips are fabricated with graphite by two distinct methods.

    In this work it is found experimentally that the appearance of surfaces in scanning tunneling microscope (STM) images can change drastically as the distance between the STM tip and sample is varied. Defects are found on gold-sputtered graphite samples which appear as protrusions in charge...

    A well defined spectrum of peaks in d2I/dV2 vs V has been obtained with a tunneling microscope immersed in liquid helium. The positions of the peaks correspond closely to the energies of the phonons of the graphite sample and the tungsten tip. We propose that electrons coupling to the bulk...

    It is demonstrated that scanning tunneling microscopy (STM) images often contain three-dimensional ghost images of the tunneling tip. These ghost images directly reflect the shape of the tip, as is proven by comparing them with tip indentations made in Si. Tip images appear as a set of identical...
