The resolution of conventional electron microscopy is not limited by electron wavelength, but by the large aberrations of electron lenses.
2.
The integer number N is determined by the width of the point contact and roughly equals the width divided by half the electron wavelength.
3.
In our current understanding of physics, the Bohr model is called a semi-classical model because of its quantization of angular momentum, not primarily because of its relationship with electron wavelength, which appeared in hindsight a dozen years after the Bohr model was proposed.

If the electron wavelength can't be reduced, is it conceivable to do the same thing with muons, creating a coherent standing wave pattern, and pump the muons to such tremendous speed that their lifespan is extended for relativistic reasons ? talk ) 21 : 53, 2 April 2016 ( UTC)
