  1. 16. Setup for Micro Photo- and Electro-Luminescence of Optoelectronic Device Structures

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Yuxuan Sun; [2015]
    Keywords : Photoluminescence; Photoluminescence setup; Electroluminescence; Optoelectronic device;

    Abstract : Photoluminescence (PL) is an optical emission induced by photon absorption in a material where electrons are excited from the ground state to excited states, then relax to the lowest excited states and recombine radiatively. The PL emission provides vital information on bandgap energy, material purity and crystal quality. READ MORE

  3. 17. Hall Measurement on Regrown Nanowires

    University essay from Lunds universitet/Fysiska institutionen

    Author : Sudhakar Sivakumar; [2015]
    Keywords : Hall measurement; InGaAs; III-V semiconductor; ballistic; transport properties; mobility; sheet carrier concentration; Physics and Astronomy;

    Abstract : Ternary semiconductor alloys like $In_xGa_{1-x}As$ have lured competing attention in connection to sub-50 nm high performance, low power, planar Complementary Metal Oxide Semiconductor technology. This compound semiconductor owes its popularity to excellent bulk carrier mobility, minority carrier diffusion constant, small bandgap, high electron injection velocity and its capability to take Moore's law beyond silicon platform.

  4. 18. Leakage current and breakdown of HfO2/InGaAs MOS capacitors

    University essay from Lunds universitet/Fysiska institutionen

    Author : Edvin Winqvist; [2015]
    Keywords : breakdown; leakage; ingaas; hfo2; Physics and Astronomy;

    Abstract : With the constant downscaling of transistors, silicon as a production material is falling out of favour because of increasing power consumption when the size of devices becomes smaller. Compound materials from group III-V in the table of elements are promising candidates to replace silicon. READ MORE

  5. 19. Current voltage characterization of high-k oxide on InGaAs substrate

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Muhammad Ismail; [2014]
    Keywords : Physics and Astronomy;

    Abstract : Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. READ MORE

  6. 20. 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
