Smooth Quantum Hydrodynamic model vs. NEMO Simulation of Resonant Tunneling Diodes

The smooth quantum hydrodynamic model is an extension of the classical hydrodynamic model for semiconductor devices which can handle in a mathematically rigorous way the discontinuities in the classical potential energy which occur at heterojunction barriers in quantum semiconductor devices. Smooth QHD model simulations of the current-voltage curves of resonant tunneling diodes are presented wh...

Simulation of Resonant Tunneling Diodes Using ATLAS

This article describes a model for Resonant Tunneling Diodes (RTDs) implemented within ATLAS framework. The model is based on a self-consistent solution of Poisson and Non-Equilibrium Green’s Function (NEGF) equations with an effective mass Hamiltonian. Simulation results are presented for generic GaAs and SiGe RTDs.

Current fluctuations in double-barrier quantum well resonant tunneling diodes

The measurements of the spectral intensity of the current fluctuations in double-barrier quantum well resonant tunneling diodes as a function of temperature and bias current are reported. Two types of devices were studied: one with AlAs barriers and GaAs well and contact regions, and the other has Alo,,Gae,As barriers. The frequency range covered is 1 Hz-100 kHz and the temperature range is 78-...
