2014-10-28 Electrons and photons:

Hi Bob,  I don't think you scales are right.  There are certainly no nm photons or we would have seen them already.  Electrons swap and change positions all the time and these changes result in emission

2014-05-30 Gap 1 nm:

It will be almost impossible to create a metal plate which has no imperfections larger than 10nm over a distance of 1 m.  That will be the first almost impossible task.  Then to take two of these perfect

2014-05-17 Grapheme:

Hi Marian,    Once you get two sheets of graphene, there is no way you will be able to stop these two surfaces to attach to each other.  The graphene sheets are very flexible.  If you can fill the gap

2014-05-12 It can produce a device according to the pictures attached?:

Looking at the image, the main problem you will face is related to the scales.  In order to produce something in the nm size, you work at elevated magnifications.  That makes the larger scale stuff much

2014-05-06 Gap 1 nm:

You can use a focussed ion beam to make a 1nm line in a material that is about 30nm thick.  the length of line you can make would be about 200nm.  Graphene falls apart if you cut a line in it, since it
