nextnano - Software for
semiconductor nanodevices

In this tutorial we calculate the transmission coefficient $T(E)$ as a function of energy $E$. We consider the following pedagogical examples we learn in undergraduate quantum mechanics courses.

• Single potential barrier
• Step potential
• Quantum well
• Double potential barrier

To calculate transmission spectra with nextnano++, we use Contact Block Reduction (CBR) method (see also documentation). This tutorial is an analog of nextnano3 tutorial.
