Quantum Physics - Infinitely vs Finite depth quantum well

Click For Summary
SUMMARY

The discussion focuses on the differences in energy and wave functions of electrons in finite versus infinite depth quantum wells. In a finite depth quantum well, the probability of finding an electron outside the well is non-zero, while in an infinite well, this probability is zero. The wave function exhibits sinusoidal behavior within the well for both cases, but is zero outside in the infinite well. Participants are encouraged to utilize the Schrödinger equation and consider boundary conditions to solve related problems.

PREREQUISITES
  • Understanding of the Schrödinger equation

You need to write the Schrödinger equation and look for solutions with boundary conditions. For finite well probability of existence of electron out side the well will be non-zero whereas for infinite well the probability will be zero. Wave function will be sinusoidal inside and outside it will be zero for infinite well. look up for a good reference book and work on these problems. See how Heisenberg principle is also obeyed for both of these.
