The scanning tunneling microscope is essentially a very sensitive profilometer that uses quantum mechanical tunneling as the sensing method. scanning tunneling microscope advantages and disadvantages STM is a powerful instrument that is used for imaging surfaces at the atomic level while AFM is one of the primary tools for imaging, measuring, and manipulating matter at the Nano-scale. In addition, it has the capability to readily store the data digitally for further processing. This allows a 3D picture of the surface to be created. The Scanning Tunneling microscopy allows researchers to collect and study images at an atomic level, and they can also alter the environment to yield different results. It is capable of imaging objects at ten times the lateral resolution, to 0.1 nanometer. A small metallic probe, . STMs are helpful because they can give researchers a three dimensional profile of a surface, which allows researchers to examine a multitude of characteristics, including roughness, surface defects and determining things about the molecules such as size and conformation. scanning tunneling microscope advantages and disadvantages Advantages and Disadvantages •No damage to the sample •Spectroscopy of individual atoms •Relatively Low Cost •Samples limited to conductors and semiconductors Scanning Tunneling Microscopy. LINK OF " SCANNING TUNNELLING MICROSCOPE ( STM ) " VIDEO *****https://youtu.be/iKhydJV0ajs ABOUT THE CHANNEL *****. INTRODUCTION The scanning tunneling microscope (STM) is a magnificent microscope ever built. By bringing the tip very close to the surface, and by applying an electrical voltage to the tip or sample, we can image the surface at an extremely small scale - down to resolving individual atoms. Quantum mechanics is the theoretical basis for tunneling. The other disadvantage is the tip might The Scanning Tunneling Microscope (STM) - The advantages of Atomic ...
