I am generating random numbers (I built a dungeon dice roller using my circuit), but my ulterior motive is to produce damaged NP junctions, and then look at them with an electron microscope and microprobe. I'd like to see what tunneling damage looks like.
Interesting !is that why you went for TO-18 (tin can) transistors then ?Yours, TonyWilk
Tunneling as you know, is the process of an electron moving through an insulator without actually being in the insulator.
Not quite, it is electrons passing through a barrier that you not expect because that barrier is higher than the energy in the electron. Typically the barrier is caused by a PN junction in the silicon. Not really anything to do with insulators.
I've learned a new engineering term here - barrier.
This a very slow old dual opamp - GBW product only 1MHz.
Yes, I have read that as well, and it fascinated me. Tunneling as you know, is the process of an electron moving through an insulator without actually being in the insulator. That is, it disappears from one location, and appears in another without occupying any space in between. Similar to how electrons move from one energy level to another in an atom, emitting a photon equivalent to the energy difference in the process.
Note you're using a LM2924.This is a very slow old dual opamp - GBW product only 1MHz.I hope you're not expecting any gain at 1MHz...There are much better devices around these days.Allan
OpAmp and Comparator actuallyYours, TonyWilk
...and I had 2 of them in a drawer.
A reaction requires a certain amount of "activation energy" in order to happen. It's essentially the same thing, right?
I'm interested in your statement Mark, that electrons have no volume. I use electron diffraction, SEM and atomic force microscopy, all of which use electron volume (or at least cross-sectional area.) How should I reconcile those two concepts?
