nope, I still don't understand much of how they work, though I believe its the change in the electron energies that force it to change its electron shell position
<nmz787>
so bandgap is the energy difference between different electron orbitals in an atom or the area around it
<nmz787>
some orbitals are able to be conduction paths
<nmz787>
sometimes when electrons fall through the orbitals they release photons
<nmz787>
a good book to read is Feynman's QED
<nmz787>
it's good for the common person to read, so you'll be fine with it
<nmz787>
electron speed is dependent on the voltage at some vacuum level
<nmz787>
or accel i guess
<nmz787>
higher voltage TEM SEM can achieve higher resolution because the faster electrons diverge less during emission to signal capture
<nmz787>
i believe

B0101: regarding pumps and acid resistance, just get a peristaltic pump and some teflon tubing, or viton
