2. Optical Characterization of Quantum-Dots-in-a-Well Infrared Photodetectors Under External Perturbations
University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)Abstract : In this project we have used Fourier transform infrared spectroscopy to study the photoresponse of two different types of quantum dot-in-a-well infrared photodetectors (DWELL QDIPs). The basic task was to compare the photoresponse of these two detectors, and to study the influence of external resonant laser pumping on the photoresponse. READ MORE

3. Comparative study of infrared photodetectors based on quantum wells (QWIPs) and quantum dots (QDIPs)
University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)Abstract : This master’s thesis deals with studies of lateral and vertical carrier transport Dot-in- a-Well (DWELL) Quantum Dot Infrared Photodetectors (QDIPs). During the pro ject, devices have been developed and tested using a Fourier Transform Infrared (FTIR) spec- trometer with the purpose to find the processes governing the flow of photocurrent in the different kinds of detectors, the dark current magnitude in the vertical Quantum Dot Infrared Photodetector (QDIP) and the Quantum Well Infrared Photodetector (QWIP) and the light polarization dependences for the vertical QDIP and the QWIP.
