**1. The Problem Statement**

An electron of effective mass m* = 0.2m

_{e}and energy E = 0.1 eV hits a barrier of height 0.4 eV and width t = 5 nm. What is the probability of transmission through the barrier? Use the simplest estimate which is an exponential function.

## Homework Equations

I think the Schrodinger equation?

## The Attempt at a Solution

First let me just say that the professor stated that the only prerequisites for this course were the first two introductory classes in physics, which at my university covers mechanics, fluids, electricity and magnetism. I have never taken any course in quantum mechanics or any advanced physics. After Googling around for a while, I learned that this was called a "Rectangular Potential Barrier" problem and requires using the Schrodinger equation(s) to solve. I'll be honest,

*the only thing I know about Schrodinger is the cat*. Now having said that,

**I am completely at a loss for where to even begin on this problem**. If someone could point me in the right direction (possibly towards some decent lecture notes on the topic) that would be great.

Thanks in advance!
