We present the results of a comprehensive model for the electric noise simulation of a kind of nano-optoelectronics device: AlGaAs/GaAs long-wavelength quantum well infrared photodetectors (LW-QWIPs) in dark conditions by assuming a three-dimensional carrier transport in the barriers where the electrical field are obtained in a self-consistent way. This model takes into account all the fundamental mechanisms involved in the device detection process. The electrical field distribution, dark currents, electrical noise are carefully calculated and analyzed. The numerical results also explain well our experimental observations.
