Question

Two copper nanowires are insulated by a copper oxide nano-layer that provides a 10.0-eV potential barrier.
1. Estimate the tunneling probability between the nanowires by 7.00-eV electrons through a 5.00-nm thick oxide
layer.
2. What if the thickness of the layer were reduced to just 1.00 nm?
(Hint: the rest mass of the electron (m) = 511 keV/c, ħ = 0.1973 keVnm/c)
