  1. 1. Tailoring the Optical Response of III-V Nanowire Arrays

    Författare :Mahtab Aghaeipour; Håkan Pettersson; Mats-Erik Pistol; Nicklas Anttu; Lars Samuelson; Constance J. Chang-Hasnain; NanoLund: Center for Nanoscience; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V nanowires; absorption; optical modes; photovoltaics; III-V nanowires; absorption; optical modes; photovoltaics; Fysicumarkivet A:2017:Aghaeipour;

    Sammanfattning : Semiconductor nanowires show a great deal of promise for applications in a wide range of important fields, including photovoltaics, biomedicine, and information technology. Developing these exciting applications is strongly dependent on understanding the fundamental properties of nanowires, such as their optical resonances and absorption spectra. LÄS MER

  3. 2. Electrical Characterisation of III-V Nanowire MOSFETs

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MOSFET; TFET; III-V; Nanowire; Hysteresis; Low-Frequency Noise; Random Telegraph Noise; cryogenic; Reliability; Radio Frequency; Small-Signal Model;

    Sammanfattning : The ever increasing demand for faster and more energy-efficient electricalcomputation and communication presents severe challenges for the semiconductor industry and particularly for the metal-oxidesemiconductorfield-effect transistor (MOSFET), which is the workhorse of modern electronics. III-V materials exhibit higher carrier mobilities than the most commonly used MOSFET material Si so that the realisation of III-V MOSFETs can enable higher operation speeds and lower drive voltages than that which is possible in Si electronics.

  4. 3. Magnetooptical properties of dilute nitride nanowires

    Författare :Mattias Jansson; Irina A Buyanova; Weimin Chen; Jan Eric Stehr; Hannah Joyce; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Sammanfattning : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

    Sammanfattning : Traffic accumulated by cars is responsible for considerable problems in our cities. The problem is partly about the negative effects on human health due to harmful particulate emissions, noise, traffic accidents and sedentary lifestyles, partly about the space it occupies, which leads to congestion, and the fact that valuable land is taken up by road infrastructure and parking lots.
