Tinker with quantum transport models! Download the MATLAB scripts used to demonstrate the physics described in Supriyo Datta\‘s book Quantum Transport: Atom to Transistor. These simple models are less than a page of code, and yet they reproduce much of the fundamental physics observed in experiments.

This presentation shows that double barrier structures can show unity transmission for energies BELOW the barrier height, resulting in resonant tunneling. The resonance can be associated with a quasi bound state, and the bound state can be related to a simple particle in a box calculation.

A resonant tunneling diode (RTD) is a type of diode with a resonant tunneling structure that allows electrons to tunnel through various resonant states at certain energy levels. RTDs can be fabricated using many different types of materials (such as III-V, type IV, II-VI semiconductors) and different types of resonant tunneling structures (such as heavily doped pn junction in Esaki diodes, double barriers, triple barriers, quantum wells, quantum wires or quantum dots). …

In quantum mechanics, quantum tunnelling is a micro nanoscopic phenomenon in which a particle violates the principles of classical mechanics by penetrating a potential barrier or impedance higher than the kinetic energy of the particle. A barrier, in terms of quantum tunnelling, may be a form of energy state analogous to a “hill” or incline in classical mechanics, which classically suggests that passage through or over such a barrier would be impossible without sufficient energy. The two …
