I thought you said you bought it used. Somebody took you for a ride John.
Seriously though, you really think defects caused by a hard physical process on the edge of a thin film has anything to do with how a 12 guage ETP copper wire conducts electricity?
I've got a bridge to sell you.

Since John likes fishing through book indexes to try to baffle people with irrelevancies, he ought to start talking about surface plasmons. It sounds much cooler than "grain boundaries."
I'll expect a commission check.
As opposed to going to the cafeteria and asking the leading edge researchers?
Well, I guess buying used books is good enough for people like you..I prefer being far more advanced in my understandings.
I just went through a 1942 book on lathe principles, and another on watchmakers lathes...I love old books, so much has been lost.

I used to be responsible to maintain and was intimately familiar with a one-off SEM for the Chemistry guys at LLNL ..... It didnt destroy nor damage nor alter the surface of the object being scanned in any way.
In fact, if it did so via heat etc, it would have blown up the SEM's LN cooled input detector as they were looking at unburnt High Explosive material (HE)!

Do the second. There's about 6.5 billion people out there, of whom 6.2 billion use metric.
When looking at edge structures that require very little energy input to change state (room temp sufficing for the purpose), an e-beam can certainly be of concern. We're not talking about frying samples, just playing with lattice strains and defects.
edit: how did they keep it in focus? Did they coat the samples with carbon first, or were the samples conductive?

While I tend to agree with your statement, I still hate you.

JN,
When I come across it in my storage I have an old metal belt driven watchmakers lathe you could have. Don't know when I will see it but when I do it is yours. I gave an entire watch and clockmaker's tool set to a museum somewhere in Santa Barbara, CA. I have a nice grandfather clock I need to fix, haven't worked on anything like it but used to fix pocket watches when I was much younger.

Get in line.

It did not happen.... I could see down to a cluster of atoms -- a molecule !
The sample was coated (one molecule thick) with various pure metals for various reasons and materials being observed. Gold was one of them.
The key, I found, much to the Chemists delight, was the zero offset in the direct coupled amps needed to be rezeroed from time to time (I had not invented the concept of dc-servo those circuit, yet). So tell your tech support to dc zero the thing's every amp stage. Have them make it a regular scheduled part of a calibration process. That alone should be good for a salary raise.

Nice impulse response and square w transfer. I like it. I also have 'something' interesting.
