This Demonstration shows the reflection and transmission coefficients for a Dirac particle with spin up and mass ... impinging on a sharp semi-infinite barrier of variable height ... On the left we have the standard solution; on the right we have imposed the alternative boundary condition that for all energies the transmitted wave moves to the right. All energies ... and ... ) are expressed in terms of the fixed incoming energy ... . You are invited to vary the mass ... , and especially look at the limit of zero mass (of relevance in graphene).
