## Homework Statement

An electron of energy E = 2.2 eV is incident on a barrier of width L = 0.7 nm and height Vo = 3.2 eV as shown in the figure below. (The figure is not drawn to scale.)

What is the probability that the electron will pass through the barrier?

The transmission probability is?

## Homework Equations

T=Ge^(-2kL)

G=16(e/v)(1-e/v)

k=sqrt(2m/(h/2∏)^2(U-E)

## The Attempt at a Solution

So I thought this was straight forward and was putting all the values into the formulas and I keep getting 0. Which is not correct...is there something I am overlooking?
