Question

An electron with kinetic energy E = 3.10 eV is incident on a barrier of width L = 0.230 nm and height U = 10.0 eV

(a)

What is the probability that the electron tunnels through the barrier? (Use 9.11 10^-31 kg for the mass of an electron, 1.055 ✕ 10⁻³⁴ J · s for ℏ, and note that there are 1.60 ✕ 10⁻¹⁹ J per eV.)

What is the probability that the electron is reflected?

What If? For what value of U (in eV) would the probability of transmission be exactly 25.0% and 50.0%?

c) 25.0%

d) 50.0%
