Scanning Tunneling Microscopy Analysis

Scanning tunneling microscope (STM) allows observation of the arrangement state of a single atom on the surface of materials, facilitating the analysis of physical and chemical properties related to the surface electronic behavior in real time. STM can product atomic images of material surfaces and provide a three-dimensional profile of the surface, which is important for determination of surface roughness, observation of surface defects and measurement of the size and conformation of molecules and aggregates on the surface. It is widely used in surface science, material science, life science and so on.

STEMart can conduct scanning tunneling microscopy analysis on metals to provide atomic images of metal surfaces.

Test Capabilities

• Observe local surface structure of a single atomic layer
• Obtain real-time three-dimensional image of the sample surface in real space
• Obtain information about the surface electronic structure, such as state density, surface electron trap, charge density wave, change of the surface potential barrier, and the energy gap structure
• Realize movement and manipulation of atoms and molecules
