1. Type-II interband quantum us dot photodetectors

College dissertation from Stockholm. KTH Royal Institute of Technology

Abstract. Photon detectors according to single-crystalline materials are of curiosity for top performance imaging applications because of their low noise and fast response. The main detector materials for sensing within the lengthy-wave length infrared (LWIR) band (8-14 ┬Ám) are presently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) utilized in intraband-based quantum-well infrared photodetectors (QWIPs).

2. Near-infrared photodetectors according to Si/SiGe nanostructures

College dissertation from Institutionen fr fysik, kemi och biologi

Abstract. Two kinds of photodetectors that contains Ge/Si quantum dots happen to be fabricated according to materials grown by molecular beam epitaxy and characterised with several experimental techniques. The goal ended up being to study new device architectures using the implementation of Ge nanostructures, to be able to obtain high recognition efficiency within the near infrared range at 70 degrees.

3. Exciton-plasmon interactions in metal-semiconductor nanostructures

College dissertation from Stockholm. KTH Royal Institute of Technology

Abstract. Semiconductor quantum dots and metal nanoparticles feature quite strong light-matter interactions, that has brought for their use within many photonic applications for example photodetectors, biosensors, components for telecommunications etc.Under illumination both structures exhibit collective electron-photon resonances, described within the frameworks of quasiparticles as exciton-polaritons for semiconductors and surface plasmon-polaritons for metals.

4. Light manipulation in micro and nano photonic materials and structures

College dissertation from Stockholm. KTH Royal Institute of Technology

Abstract. Light manipulation is a vital approach to boost the light-matter interactions in micro and nano photonic materials and structures by generating usefulelectric field components and growing some time and pathways of sunshine propagationthrough the micro and nano materials and structures. For instance, quantum wellinfrared photodetector (QWIP) cannot absorb normal incident radiation so thatthe generation of the electric field component that is parallel towards the original incident direction is really a necessity for that purpose of QWIP.

5. Experimental and theoretical study of quantum us dot resonant tunneling diodes for single photon recognition

College dissertation from Stockholm. KTH

Abstract. Single photon recognition includes a broad application within the medical, telecommunication, plus infrared imaging fields. Within this thesis I present my operate in studying quantum us dot (QD) resonant tunneling diodes (RTD) for single photon recognition. The unit was processed by means of a totally free-standing small-area air bridge. Find Out More
