question 48

Multiple Choice

Tunneling: An electron with kinetic energy 2.80 eV encounters a potential barrier of height 4.70 eV. If the barrier width is 0.40 nm, what is the probability that the electron will tunnel through the barrier? (1 eV = 1.60 × 10^-19 J, m_el = 9.11 × 10^-31 kg, ħ = 1.055 × 10^-34 J ∙ s, h = 6.626 × 10^-34 J ∙ s)

• A) 3.5 × 10^-3
• B) 7.3 × 10^-3
• C) 1.4 × 10^-2
• D) 2.9 × 10^-3
• E) 3.5 × 10^-2
