Journal ArticleDOI
Three-dimensional imaging of short-range chemical forces with picometre resolution
Boris J. Albers,Todd C. Schwendemann,Mehmet Z. Baykara,N. Pilet,N. Pilet,Marcus Liebmann,Marcus Liebmann,Eric I. Altman,Udo D. Schwarz +8 more
TL;DR: This work shows force maps with picometre and piconewton resolution that allow a detailed characterization of the interaction between the surface and the tip of the microscope in three dimensions, and suggests that the excellent lubrication properties of graphite may be due to a significant localization of the lateral forces.
Journal ArticleDOI
Combined low-temperature scanning tunneling/atomic force microscope for atomic resolution imaging and site-specific force spectroscopy.
Boris J. Albers,Marcus Liebmann,Todd C. Schwendemann,Mehmet Z. Baykara,Markus Heyde,Miquel Salmeron,Eric I. Altman,Udo D. Schwarz +7 more
TL;DR: The design and first results of a low-temperature, ultrahigh vacuum scanning probe microscope enabling atomic resolution imaging in both scanning tunneling microscopy (STM) and noncontact atomic force microscope (NC-AFM) modes are presented.
Journal ArticleDOI
Three-dimensional atomic force microscopy - taking surface imaging to the next level.
TL;DR: Based on noncontact atomic force microscopy, 3D-AFM is able to provide more detailed information on surface properties than ever before, thanks to the simultaneous multi-channel acquisition of complementary spatial data such as local energy dissipation and tunneling currents.
Journal ArticleDOI
Understanding scanning tunneling microscopy contrast mechanisms on metal oxides: a case study.
Harry Mönig,Harry Mönig,Milica Todorović,Mehmet Z. Baykara,Mehmet Z. Baykara,Todd C. Schwendemann,Todd C. Schwendemann,Lucía Rodrigo,Eric I. Altman,Rubén Pérez,Udo D. Schwarz +10 more
TL;DR: It is found that depending on the bias voltage polarity, copper-terminated tips allow selective imaging of two structurally distinct surface Cu sites, while oxygen- terminated tips show complex contrasts with pronounced asymmetry and tip-sample distance dependence, which provides a conclusive understanding of fundamental STM imaging mechanisms.
Journal ArticleDOI
Achieving A-Site Termination on La0.18Sr0.82Al0.59Ta0.41O3 Substrates
Joseph H. Ngai,Todd C. Schwendemann,Anna E. Walker,Anna E. Walker,Y. Segal,Fred Walker,Fred Walker,Eric I. Altman,Chong H. Ahn +8 more
TL;DR: SrTiO 3 (STO), which is closely lattice matched to many transition metal oxides, is extensively used in part because TiO 2 -terminated surfaces exhibiting singleunit-cell steps can be achieved through etching and annealing techniques.
