Something has been bothering me about this negative resistance thing but
I couldn't put my finger on it. While in a half sleep state, I
remembered what it was. There was a peculiar statement that might not
really be connected but here is the quote from one of the articles about
Dr. Deborah Chung;
"In the experiments, two layers of carbon fibers oriented
in different directions and bound together by epoxy,
Portland cement or pressure demonstrated negative resistance
as low as -8 ohms for a contact area of one square centimeter."
Many years ago, I used to subscribe to a lot more tech publications and
there was an article about this amazing thing they had discovered with
light fiber bundles.
It seems when you have to connect fiber bundles together, the
transmittivity goes down drastically, to something like 25% (I don't
remember the exact details as it was about 10-12 years ago). At the
time I thought this was because the bundle ends didn't match up.
They found that by slicing the ends of the two bundles that were to be
joined, so that one end was at 33 1/3 and the other was at 66 2/3s, they
could instantly increase the transmittivity up to around 96%.
This always bothered me but it appeared that the ends were more likely
to come together over this wider surface area.
So is it possible that these carbon fibers 'oriented in different
directions' could be relying on a similar effect to reduce the
resistance?
