| - | ===== Transmission in 1D potential (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]]. | ||
