An electron with energy E is incident from left on a potential barrier, given by \[ gathered V ( x ) = 0 for x 0 \\ gathered \] as shown in the figure. For E 0 is of the form

An electron with energy E is incident from left on a potential barrier, given by $$\begin{array}{c}V\left(x\right)=0\text{ for }x<0\text{hfill}\\ =V_0\text{ for }x>0\text{hfill}\end{array}$$     as shown in the figure.

For E < V₀, the space part of the wave function for x > 0 is of the form
