16 For three experiments, Fig. 38-25
gives the transmission coefficient T
for electron tunneling through a po-
tential barrier, plotted versus barrier
thickness L. The de Broglie wave-
lengths of the electrons are identical
in the three experiments. The only
difference in the physical setups is
the barrier heights U. Rank the
three experiments according to U,
greatest first.

An electron is moving past the square barrier shown in Fig. , but the energy of the electron is greater than the barrier height. If E = 2U0 , what is the ratio of the de Broglie wavelength of the electron in the region x 7 L to the wavelength for 0 6 x 6 L?
The interatomic spacing in a crystal of table salt is 0.282 nm. This crystal is being
