you read me too literally.

yes carriers, but i'm not going to pretend i'm an expert in the area, I simply brought it up as an alternative view. the channels have atoms with an excess of electrons or holes respectively, but the doping is an effect at the subatomic level.

I already linked a few technical papers on the subject for those who want to know more. my point was, its not as neat as we thought. and it has EVERYTHING to do with solid state electronics

Do you mean channels in the ground plane?

no, I mean channels in the solid state devices. as in N-Channel, or P-Channel, or PNP/ NPN transistors you do know what I mean yes? the dac, the PC, the opamps, everything is partially made up of doped atoms. in the case of ESS is not truly complementary so is mostly N channel afaik, electrons flow FROM ground to a more positively charged area and holes flow TO 'ground' or a more negatively charged area. basically its the opposite of what we thought for a long time; or rather the flow can be the same, but its holes that flow that direction, not the electrons between atoms

its all covered in the links I made in that post

You can think about current as the flow of electrons, which go from negative to positive, or as the flow of holes, which go the other way. If you are reallly into semi-conductor theory it makes a difference which one you use, but otherwise you aren't likely to care. We usually use hole flow because the direction agrees with the decision that the early scientists made when they had to pick a direction to use in their calculations. It's traditional.

Nope, I simply read what you wrote - 'N channels are doped with electrons' - and corrected you because that's wrong, they're not.

Nope, that's still wrong. But as you seem not to want to learn I'll not explain a more correct view this time - you can find out for yourself

you didnt at any point explain a more correct view....par for the course...

but OK it seems carrier is just another name for hole aka charge carrier. if you actually read the whole post instead of picking a little bit to disagree with, you would see I had the correct gist of it, then linked to more knowledgable folks.

an extra electron, or one less electron charge has to come from somewhere, how do you propose they get the excess or lack of them into the implanted atoms? picking a hole in making a positively doped or negatively doped atom and implanting that, with adding or removing electrons is just argument for the sake of it

it was a novelty for **** sakeI find it interesting, but not interesting enough to devote my life to learning a new branch of science.

can you ignore a thread?

No, that's wrong. Rulers are used for measuring the direct distance between two points on a lateral plane. You used a cutting edge. This is not the same. You should read this white paper on the molecular structure of the leading edge of a continuous cast single-crystal nickel-titanium super alloy. It has neither dendritic formations or an equiaxed granular structure but is a single crystal and therefore, even under an electron microscope, has a flat edge because it has no grains. You should use a nickel-titanium super alloy cutting edge.That's what you should do. You can thank me now.

It seems that link doesn't work. Maybe try this : http://www.google.co.uk/search?q=wha...w=1092&bih=533 and follow the second result. You-know-who.

I see a pattern emerging, people ask for more detail as was done with this flawed design and at many points through both threads, then whine when the answer doesnt suit them.

then when all else fails, make a joke.

what does a ruler have to do with channels, me thinks the joke is misplaced, but I understand you had to make it at all costs

but then we always have belief.

We were talking about issues in the ground plane which is a conductor (you know copper) and suddenly we jumped into n and p channels, semiconductor doping, electron, holes... What's the relation to the ground plane?

Well, at least I used a magnifying glass
