===== 1D Transmission (CBR) =====
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 **C**ontact **B**lock **R**eduction (CBR) method (see also [[https://www.nextnano.com/nextnanoplus/software_documentation/input_file/cbr.htm|documentation]]). This tutorial is an analog of [[https://www.nextnano.de/nextnano3/tutorial/1Dtutorial_Transmission_NEGF.htm|nextnano3 tutorial]].
