1988年1月1日 · The scanning tunneling microscope (STM) promises to be a useful tool for the study of thin film deposition processes. We have imaged the growth surface of vapor-deposited gold on mica with an STM. Monatomic steps, dislocations, grain boundaries and grain topographies have been mapped for various gold thicknesses and deposition temperatures.

2018年1月1日 · Highly ordered Ag films grown on cleaved mica with a two-step procedure were characterized in detail with several techniques for surface analysis, including low-energy electron diffraction, X-ray photoemission spectra, a scanning tunneling microscope and angle-resolved photoemission spectra.

We study interfacial water trapped between a sheet of graphene and a muscovite (mica) surface using Raman spectroscopy and ultrahigh vacuum scanning tunneling microscopy (UHV-STM) at room temperature. We are able to image the graphene–water interface with atomic resolution, revealing a layered network of water trapped underneath the graphene.

An epitaxially grown Au film on a cleaved mica substrate has a stable and inert surface with (111) orientation [1]. It can be used as an alternative surface to HOPG (highly oriented pyrolytic graphite) for STM images with atomic resolution in air. Surface states in the gap of projected bulk states make possible to study

Samples prepared at various temperatures from 580 K to 890 K and evaporation rates smaller than 1 nm/s were studied by a scanning tunneling microscope (STM) under ambient conditions. Structure and defects of Au(111) surfaces were investigated …

1991年10月1日 · In this paper we report our investigation of the epitaxy of gold on mica via STM and AFM car- ried out specifically to find the conditions neces- sary to induce the growth of large-area flat faces on the Au thin film surface so that it could be used as a STM/AFM substrate.

1996年2月29日 · Imaging DNA at exceedingly low currents and high voltages prevents damaging contact in humid conditions. The STM images of DNA on mica are evidence that the STM could be used to study genomic structure on a nanometer scale.

2017年3月6日 · We show by means of scanning tunneling microscopy (STM) and Lateral Force Microscopy (LFM) that graphene can enable non-destructive visualization, with single-ion resolution, of the lateral ...

PHASIS Au(111) thin films are epitaxially grown using RF magnetron sputtering on freshly cleaved high quality Mica substrates. The films present an extremely high degree of structural quality including surfaces with well defined terraces well adapted to local probe studies. These films can be advantageously used for SPM calibration purposes.

2013年4月1日 · STM images on few-layer graphene exfoliated on mica exhibit triangular patterns. Pattern is a network of partial dislocations separating ABA and ABC stacked areas. STS shows a pronounced peak at 0.25 eV exclusively in ABA areas. Peak causes apparent height differences in STM images. Possibly caused by Fabry–Perot type interference ...
