Abstract EN
The quantum efficiency of a silicon p-υ-n photodetector is present.
The analysis to obtain the quantum efficiency takes a uniform doping concentration in each layer into consideration.
The theoretical treatment aims to investigate the effect of device parameters on the efficiency.
Three different cases of the incident light wavelengths have been considered; short wavelengths, medium wavelengths, and long wavelengths.
There is no wavelength range between them, but when the most of the incident light (about 63% or more) absorbed near the surface, it is called short wavelength, and when most of the light absorbed in υ-layer, it is called medium wavelength else called long wavelength.A high quantum efficiency at the wavelength of interest, combine with its low operating voltage and capability, make this detector a promising for use in communication systems and computer interconnections.High speed silicon p-υ-n photodetector operates at 700 nmwavelength is reported.
By using a reverse bias voltage to control υ-layer width, a high quantum efficiency of 80% is attained corresponding to υ-layer width of 5.36 m and biasing voltage of 2.182 V.The results showed that the quantum efficiency is directly proportional to the width of the υ-layer and biasing voltage.
The results are achieved with the aid of MATLAB programming tool version 8.1.0.604 R2013a.
