  1. 1. Properties of III-V/Si heterojunction fabricated by HVPE

    University essay from KTH/Tillämpad fysik

    Author : Prakhar Bhargava; [2020]
    Keywords : ;

    Abstract : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. READ MORE

  3. 2. Surface Treatment of Softwood Lignin Based Carbon Fibers for Enhanced Interfacial Adhesion : Effects of Plasma Treatment Parameters on the Creation of Surface Groups

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Yunus Gorur; [2017]
    Keywords : Lignin; adhesion; surface; carbon; fiber;

    Abstract : Lightweight design is an essential part of lowering CO2 emission, which is one of the mostimportant challenges that the automotive industry is facing today. Carbon fiber reinforcedplastics offer an enormous potential for replacing heavier structural materials like steel andaluminum, however due to their high cost and scarcity, carbon fibers are not a very feasibleoption to use in high volume production applications.

  4. 3. Kilohertz electro-optics for remote sensing of insect dispersal

    University essay from Lunds universitet/Fysiska institutionen

    Author : Sandra Török; [2013]
    Keywords : LUMBO; remote sensing; dark-field spectroscopy; insect wingbeat modulation; Technology and Engineering;

    Abstract : This thesis evaluates the possibilities of determining the flight direction of insects by analysing the wingbeat modulation pattern of the backscattered sunlight from insects. The Lund University Mobile Biosphere Observatory (LUMBO) was used during the summer of 2013 for a field campaign at two locations in Skåne, Sweden. READ MORE

  5. 4. Magneto-optical studies of optical spin injection in InAs quantum dot structures

    University essay from Funktionella elektroniska material; Tekniska högskolan

    Author : Wang Po-Hsiang; [2012]
    Keywords : optical spin injection; optical orientation spectroscopy; magnetic field; Landau level; hyperfine interaction; dynamic nuclear polarization; InAs GaAs quantum dots;

    Abstract : Optical spin injection in InAs/GaAs quantum dots (QDs) structures under cryogenic temperature has been investigated in this work using continuous-wave optical orientation spectroscopy. Circularly polarized luminescence from trions in the QDs was used as a measure for the degree of spin polarization of the carriers in the QD ground states. READ MORE

  6. 5. Synthesis of azide- and alkyne-terminated alkane thiols and evaluation of their application in Huisgen 1,3-dipolar cycloaddition ("click") reactions on gold surfaces

    University essay from Institutionen för fysik, kemi och biologi

    Author : Yohei Okabayashi; [2009]
    Keywords : Self-Assembled monolayers; Click Chemistry; Infrared Reflection-Absorption Spectroscopy; Surface Plasmon Resonance;

    Abstract : Immobilization of different bio- and organic molecules on solid supports is fundamental within many areas of science. Sometimes, it is desirable to obtain a directed orientation of the molecule in the immobilized state. READ MORE
