Electron-beam-induced current (EBIC) is a semiconductor analysis technique performed in a scanning electron microscope (SEM) or scanning transmission electron microscope (STEM). It is most commonly used to identify buried junctions or defects in semiconductors, or to examine minority carrier properties.

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
It can be theoretically shown that a scale selection module working according to this principle will satisfy the following scale covariance property: if for a certain type of image feature a local maximum is assumed in a certain image at a certain scale , then under a rescaling of the image by a scale factor the local maximum over scales in the ...
These ideas for multi-scale image segmentation by linking image structures over scales have also been picked up by Florack and Kuijper. [13] Bijaoui and Rué [14] associate structures detected in scale-space above a minimum noise threshold into an object tree which spans multiple scales and corresponds to a kind of feature in the original ...
In the 1980s, artist Keith Jennings lived with friends on a farm in St. Simons Island.He decided to kill some time by carving a face in a tree. That first tree spirit became the origin of a now 40 ...
The microscope features a combination of optical and electron-optical images; the optical image enables a "Neverlost" function so operators may navigate to any point on the sample. Sample loading takes place in four seconds (to obtain the CMOS overview image) and 30 seconds into the vacuum space via rapid transfer technology (no conventional ...
