1. 1. Automated noise measurements for very long wavelength infrared detectors

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : David Ramos Santesmases; [2019]
   Keywords : Noise; Infrared detector; QWIP; T2SL; Brus; Infraröd detektor; QWIP; T2SL;

   Abstract : The potential imaging performance of infrared (IR) detectors is dependent on the noise level in the detector pixels. Noise measurements at pixel level can therefore provide basic understanding of the intrinsic limitations of detectors. READ MORE

3. 2. Comparative study of infrared photodetectors based on quantum wells (QWIPs) and quantum dots (QDIPs)

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Conny Hansson; Krishna Kishore Rachavula; [2006]
   Keywords : Dot-in-a-Well; DWELL; Quantum Dot Infrared Photodetectors; QDIPs; Lateral carrier transport;

   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.
