The “light” at the bottom of this glowing crater is all electrons.
What you’re seeing here is a thin layer of glass with a hole chipped in it. At
the bottom of the hole, just out of the field of view, is a layer of silicon.
In the electron
A particle of dust, viewed at around 19,000x in an electron microscope.
It’s sitting on a little pedestal that it made itself out of my semiconductor
laser material - no, I didn’t give it permission. The dust particle selflessly
protected that patch of semiconductor from the harsh
Microscopic hills along a glass fracture
Here, the edge of one of my samples was chipped, and the glass had flaked off in
a ridged pattern. The ridges continued right down to the border of the chipped
area, where they became microscopic. These hills are so small that you could
An upside-down mountain, formed from dust. The whole thing is about the size of
a single bacterium.
The mountain is, as usual, not supposed to be there - it’s a piece of dust that
landed on my sample. Despite doing all my processing work in the cleanroom,
it’s
Reactive ion etcher: capable of using high-energy plasma to blast away metal,
glass, and a lot more. Also capable of running Solitaire.
To be fair, the guy using this machine is probably killing time while the
machine runs an etching process, or pumps the system down to vacuum. Otherwise
it’
Extreme close-up of tape in a scanning electron microscope.
It’s conductive carbon tape, which we use for mounting stuff in the electron
microscope, and it’s usually covered in strange craters and textures - I don’t
know what purpose those serve. Does make it look like some kind
Newton’s rings put on a microscopic show.
This is a microscope image, about 20x, of some bright bands of color that
appeared on the surface of one of my samples. They’re formed from a colorless
film of residue left behind after some IPA dried on my sample -
Someone asked me yesterday how big my samples are, and what it all looks like.
This is a zoomed-out view (only 90x!) showing a nearly edge-on view of one of
my samples, sitting on a cratered sea of carbon tape. It’s so zoomed-out that I
almost feel embarrassed asking
This entire view would fit easily inside a single cell.
The “lake” is a crater with glass at the bottom - being an insulator, glass
tends to build up charge that deflects the electron beam my microscope fires at
the sample, so very little bounces back… it appears dark. The
The lace ship.
This is some sort of dust that landed on my sample before etching - I do try to
clean dust off, but I don’t get everything removed. This particular sample had
a few of these airy, lacy dust particles - I’m not sure what they
