Imaging of liquid crystals using a tunnelling microscope

  title={Imaging of liquid crystals using a tunnelling microscope},
  author={John Stuart Foster and Jane Frommer},
Since its conception1, the scanning tunnelling microscope (STM) has been used principally to explore surfaces of well ordered inorganic solids and graphite2,3. We now report the first use of the STM to unambiguously image well defined organic adsorbates on surfaces. We have imaged individual organic molecules in a liquid crystal array on a graphite surface with the STM with nearly atomic resolution. Liquid crystals have previously been analysed by X-ray diffraction, neutron scattering… Expand
Imaging of liquid crystals with tunneling microscopy
We have used the scanning tunneling microscope (STM) to image a wide variety of organic liquid crystal molecules adsorbed onto a graphite substrate. From the images it is apparent that the STM isExpand
Anchoring structure of smectic liquid-crystal layers on MoS2 observed by scanning tunnelling microscopy
THE molecular alignment of liquid crystals on solid substrates is important both to fundamental issues in physics and biology and in practical applications such as optoelectronic devices. TheExpand
STM studies on dye molecules embedded in ordered liquid crystal structures and an approach for laser-assisted scanning tunneling microscopy
Scanning tunneling microscopy, although capable of yielding very high resolution on periodic structures, very often provides only moderate resolution on singular features. Our work aims at the use ofExpand
Scanning tunneling microscopy of chain-molecules at solid-fluid-interfaces
Scanning tunneling microscopy has been employed to investigate chain molecules, which have been self-assembled at the interface between their melts or organic solutions, and a solid flat surface of aExpand
Structure, registry and imaging mechanism of alkylcyanobiphenyl molecules by tunnelling microscopy
GRAPHITE is a popular choice as a substrate for the study of absorption of molecules on surfaces because of its relatively simple interaction with adsorbates and the ease of preparing a clean andExpand
Molecular Imaging with the Scanning Tunneling Microscope
Two classes of molecular materials can be directly investigated by scanning tunneling microscopy (STM), namely (1) organic conductors and (2) ultrathin organic layers on conducting substrates. SinceExpand

Voltage‐dependent scanning tunneling microscopy images of liquid crystals on graphite
Voltage‐dependent images of liquid crystals on graphite were observed in air by scanning tunneling microscopy (STM). Molecular rows of liquid crystals and the atomic pattern of the graphite substrateExpand


Abstract The (0001) surface of graphite has been investigated using the scanning tunneling microscope (STM) over a relatively wide area containing many unit cells. We do not observe trigonal symmetryExpand
Scanning tunneling microscopy
A scanning tunneling microscope (STM) can provide atomic‐resolution images of samples in ultra‐high vacuum, moderate vacuum, gases including air at atmospheric pressure, and liquids including oil,Expand
Tunneling microscopy of graphite in air
Images of graphite have been recorded with a scanning tunneling microscope operating in air at ambient pressure. The results, which are in agreement with theory and previous experiments in vacuum,Expand
Scanning tunneling microscopy
Abstract An overview of the status of Scanning Tunneling Microscopy (STM) is given. So far, the method has been applied mainly to surface structures. Examples are given for reconstructions on metalExpand
The structure of smectic A phases of compounds with cyano end groups
2014 The smectic layer spacings (d) have been determined for a number of cyano derivatives which have an anomalous d/l ratio of ~ 1.4, where l is the molecular length. It is shown that the quantityExpand
