What else can I help you with?
Who invented the scanning tunneling microscope?
a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen
What is an Esaki diode?
A diode is a semiconductor electrical component that allows an electric current in only one direction. A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).
What type of mining would most likely be used if a resource is concentrated in deep pockets in ground that is safe for tunneling?
Open Pit Mining
Current in which electrons flow in the same direction is called?
It's alternating current
Is the base current smaller or larger than the emitter current?
The base current of the emitter current is smaller.
What do you mean by tunneling?
tunneling
How large do you think the needle is in the scanning tunneling mircoscope?
The needle in a scanning tunneling microscope is typically on the nanometer scale, ranging from 1 to 10 nanometers in diameter. Its sharp tip allows for atomic-scale resolution during imaging by detecting the tunneling current between the tip and the surface being scanned.
What do you mean by tunneling process?
it means tunneling process
What is tunnelling effect in STM?
The tunneling effect in STM (scanning tunneling microscope) refers to the phenomenon where electrons tunnel through a vacuum barrier between a sharp tip and a sample surface. This allows for the measurement of electron density and surface topography at the atomic scale. The STM measures the tunneling current resulting from this effect to create high-resolution images of surfaces.
What part of an atom is detected by STM?
The electron cloud surrounding the nucleus of an atom is detected by an STM (Scanning Tunneling Microscope). This technique measures the tunneling current between the tip of the microscope and the atomic surface, allowing visualization of the electron distribution.
When was Norwegian Tunneling Society created?
Norwegian Tunneling Society was created in 1963.
What do the scanning tunneling microscope and the one-angstrom microscope allow scientist to see?
The scanning tunneling microscope allows scientists to see individual atoms on a surface by detecting the tunneling current between the microscope tip and the sample. The one-angstrom microscope is a hypothetical concept that would potentially allow scientists to visualize atomic details with even higher resolution.
What does a scanning tunneling microscope allow scientists to see?
A scanning tunneling microscope allows scientists to see individual atoms and molecules on a surface by measuring the electrical current that flows between the microscope's probe tip and the sample surface. This technology provides high-resolution imaging of surface structures, enabling the visualization of atomic-scale details.
Who invented the scanning tunneling microscope?

How a scanning tunnel microscope works?
A conducting tip is brought very close to the surface of the object of interest Some electrons can "tunnel" through the space between the object and the conducting tip, creating a current. The way current varies as the tip is moved across the surface is used to determine the shape of the surface.
Do you use the scanning tunneling microscope for live or dead samples?
The scanning tunneling microscope (STM) is typically used for imaging surfaces of materials at the atomic level, regardless of whether the sample is alive or dead. The STM works by scanning a sharp metal tip over the sample surface and detecting the tunneling current between the tip and the surface, allowing for atomic-scale resolution imaging. It is commonly used in both materials science and nanotechnology research.
What is a scanning tunneling microscope?
(STM) uses an electron beam not only to image things, getting resolution at the atomic level, but actually manipulate them too -a powerful technique for viewing surfaces at an atomic level. -invented by Gerd Binnig and Heinrich Rohrer -based on the concept of quantum tunneling
