An electron with total energy E = 5.1 eV approaches a barrier of height `U_(h) = 6.8 eV` and thickness L = 750 pm. What percentage change in the transmission coefficient T occurs for a `1.0%` change in (a) the barrier height, (b) the barrier thickness, and (c) the kinetic energy of the incident electron?

Explanation

To solve the problem, we need to analyze the transmission coefficient \( T \) for an electron tunneling through a potential barrier. The transmission coefficient is given by:

\[ T = e^{-2\gamma L} \]

where \( \gamma \) is defined as:
