Resonant Tunneling Diode: Double-Barrier Nanostructure

Interactive 3D resonant tunneling diode: tune the barrier height, barrier width and quantum-well width of a double-barrier GaAs/AlGaAs nanostructure and watch the transmission resonance, the electron wavefunction and the negative-differential-resistance I-V curve respond in real time.

This simulator solves the 1-D Schrödinger equation exactly (transfer-matrix method) for an electron crossing a double-barrier quantum well — the emitter-barrier-well-barrier-collector geometry at the heart of a real resonant tunneling diode. Drag the barrier height, barrier width and well width to reshape the transmission resonance, then sweep the bias voltage to watch the resonant level cross the emitter's Fermi energy and produce negative differential resistance: current that falls as voltage rises, the hallmark of quantum-confined nanoelectronic devices.

⚙ Under the hood

Simulate quantum resonant tunneling through a double-barrier GaAs/AlGaAs nanostructure: tune the barrier height, barrier width and quantum-well width, sweep the bias voltage, and watch the transmission resonance drive a real negative-differential-resistance I-V curve.
