  1. 1. Characterization of single InP Nanowire-based Avalanche Photodetectors

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

    Author : Virginia Boix De La Cruz; [2016]
    Keywords : Photodetectors; Nanotechnology; Nanowires; IndiumPhosphide; Semiconductors; Physics and Astronomy;

    Abstract : Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. READ MORE

  4. 3. Automation of a long-term measurement of organic solar cells

    University essay from Uppsala universitet/Teknisk-naturvetenskapliga fakulteten

    Author : Anton Fjodorov; [2011]
    Keywords : automation; long-term; measurement; organic; solar; cell; programming; Python; SMU; Keithley; IAPP;

    Abstract : Organic solar cells represent a clean and renewable source of energy. They are cheaper and handier than conventional silicon solar cells, but have lower efficiency and shorter lifetime. This project was conducted to assist a two years' outdoor study on the lifetime of organic solarcells, in order to better understand the lifetime-affecting factors. READ MORE

  5. 4. Setup of pulsed IV system and characterization of magnetic nanocontacts and microwires

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

    Author : Shuo Kong; Xu Sun; [2011]
    Keywords : Low signal measurements; Pulse delta IV measurements; Nanodevices;

    Abstract : The development of resistance measurement techniques is very important for characterization of future nanoelectronics. Pulsed IV measurement techniques are very useful for accurate resistance measurements on nanoscale samples because of the efficient removal of e.g. EMF errors. READ MORE
