Abstract

In this paper, selective energy contacts are used to design a multi-wavelength optical photodetector. Here, 3D spherical shape quantum dots with quantum well-based energy selective contacts are simulated. The introduced technique helps us to design a novel photodetector that can simultaneously detect multi-wavelengths. These wavelengths can include several ultraviolet wavelengths or several infrared wavelengths or a combination of them. This detection can be achieved by intera-band and inter-band transitions in quantum dot-based Super-lattices. To detect higher wavelengths, intra-band transmissions and for lower wavelengths, inter-band transmissions can be used. In this work, suitable energy selective contacts are designed using quantum wells. Also, quantum dots with different radii are used to detect multi-wavelengths simultaneously. Finally, as an application of this structure, the results have been presented for two quantum dots capable of simultaneous detection of two UV radiations, simultaneously. The detector can be further improved by applying several quantum dots with different sizes, shapes and materials and using more ESCs.
