  1. 1. Image dipoles and polarons in organic semiconductors

    Författare :Yongzhen Chen; Mats Fahlman; Xianjie Liu; Yiqiang Zhan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Interface dipole; Polaron; Conjugated polymer; Photoelectron spectroscopy; N-type doping; Electron transport material;

    Sammanfattning : The rapid development of organic electronics depends on the synthesis of new π-conjugated molecules/polymers and the exploration of fundamental physics. However, most of the efforts have been concentrated on the former, leading to a lack of thorough understanding of many important concepts, which will become the ultimate limiting factor for overall performance and applications.

    Sammanfattning : Diamond is a unique material with excellent properties. As a result of the development within the area of CVD synthesis, doping and surface functionalization, diamond has become a strong candidate for use in electrochemical, electronic and biomedical applications. LÄS MER

  4. 3. Synchrotron X-ray based characterization of technologically relevant III-V surfaces and nanostructures

    Författare :Andrea Troian; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; III-V semiconductors; high-k oxides; passivation; doping; XPS; AP-XPS; SPEM; XRF; full field X-ray diffraction microscopy; Fysicumarkivet A:2019:Troian;

    Sammanfattning : Innovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) studied here.

  5. 4. Doping of high-Al-content AlGaN grown by MOCVD

    Författare :Daniel Nilsson; Anelia Kakanakova- Georgieva; Erik Janzén; Michelle Moram; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The high-Al-content AlxGa1-xN, x > 0.70, is the principal wide-band-gap alloy system to enable the development of light-emitting diodes operating at the short wavelengths in the deep-ultraviolet, λ < 280 nm. LÄS MER

  7. 5. Doping and Density of States Engineering for Organic Thermoelectrics

    Författare :Guangzheng Zuo; Martijn Kemerink; Ergang Wang; Mariano Campoy-Quiles; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric materials can turn temperature differences directly into electricity. To use this to harvest e.g. waste heat with an efficiency that approaches the Carnot efficiency requires a figure of merit ZT larger than 1. LÄS MER
