Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its ...
Scanning electron microscopy (SEM) is an advanced analytical tool that massively outstrips the capabilities of traditional light microscopy. Using visible wavelengths of light on the 400 – 700 ...
The last time we used a scanning electron microscope (a SEM), it looked like something from a bad 1950s science fiction movie. These days SEMs, like the one at the IBM research center, look like ...
Atomic-scale detail is now possible with photons, thanks to a cooled-down silver tip and a clever use of plasmonics.
We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable too… ...
The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels through electromagnetic fields and lenses, which focus the beam down toward the sample ...
Atomic Force Microscopy (AFM): Atomic Force Microscopy, another prominent SPM technique, uses a cantilever with a sharp tip to physically touch the surface and measure the force between the tip and ...
I built a 3D printed, scanning laser confocal microscope so I could collect 3D surface topology and profilometry data! The microscope stage is based on an OpenFlexure "Delta" stage, and the ...
A common example is knock-on damage, whereby an intense electron beam can shift the positions of atoms in a sample. Damage or resolution “Reducing the electron dose would limit the sample damage, but ...
You didn't wake up this morning thinking that a tick under a scanning electron microscope was going to be the coolest thing you saw all day, and yet here you are. After discovering some ticks ...
