1. Numerical Simulations of Resonant Tunnelling Diodes
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

2. Stacked Dual Narrowband Organic Near-Infrared Photodetectors
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. READ MORE

3. A framework for designing a modular muffler system by global optimization
University essay from KTH/Optimeringslära och systemteoriAbstract : When creating a muffler to be installed on a noise generating machine, the design parameters as well as the placements of sound attenuating elements has to be optimized in order to minimize the sound coming out of the equipage. This is exemplified in a small project task for students of a basic course in optimization at KTH. READ MORE
