STM Meaning and
Definition
-
STM is an acronym that stands for "Scanning Tunneling Microscopy" or "Scanning Tunneling Microscope." It refers to a powerful scientific technique used to study and manipulate individual atoms and molecules on a solid surface at an atomic resolution.
A scanning tunneling microscope is an instrument that utilizes the principle of quantum tunneling to generate high-resolution images of surface topography and electronic structures. It comprises a sharp conducting probe tip positioned just a few atomic diameters away from the surface under investigation. By applying a small voltage between the probe and the surface, a tunneling current flows.
The STM operates based on the principle that the tunneling current exponentially depends on the distance between the tip and the sample. By meticulously scanning the tip over the surface and precisely measuring the tip's height, the sample's topography can be visualized at an atomic scale. This revolutionary technique has provided crucial insights into surface science, nanostructures, and nanotechnology.
Additionally, the STM technique can also be applied to manipulate individual atoms or molecules by positioning the tip close to a specific atom and utilizing the tunneling current to induce atomic-scale movements. This ability to manipulate matter at the atomic scale has opened up new avenues in nanotechnology and has allowed scientists to explore new material properties and develop innovative nanostructures.
In summary, STM refers to the technique of scanning tunneling microscopy and the related instrument, the scanning tunneling microscope, which are used to study and manipulate individual atoms and molecules on a solid surface at an atomic resolution.
