Quantum Physics Particle in 1D box Finite Potential Scrödinger Equation
Inside: V(x) = 0
Outside: V(x) = U0
The solutions and it’s derivative must match at the boundary

6. Quantum Physics Tunneling - Def
Outside: V(x) = 0
Inside: V(x) = U0
Tunneling probability T that the particle gets through the barrier is proportional to the square of the ratio of the amplitudes of the sinusoidal wave function on the two sides of the barrier.

7. Quantum Physics Tunneling - Example - Electron
A 2.0 eV electron encounters a barrier 5.0 eV heigh.
What is the probability that it will tunnel through the barrier
if the barrier width is a) 1.00 nm b) 0.50 nm ? a) b)
