    Sammanfattning : In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. LÄS MER

  4. 3. Electrical and Optical Properties of AlGaAs/GaAs Aperiodic Superlattices and Resonant Tunneling Diodes. Theory, Design and Applications

    Författare :Simon Mang Cao; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exciton-assisted transport; miniband; high-speed quantum electronics; optical properties; ultrafast optoelectronics; field-induced transport; irregular superlattices; nanometer-scale heterostructures; laser diodes; resonant tunneling;

    Sammanfattning : The objective of the work presented in this thesis is to study quantum transport and optical properties of aperiodic superlattices and resonant tunneling diodes using III-V semiconductor heterostructures grown by molecular beam epitaxy. The study follows a procedure of theoretical modeling, computer-aided design and simulation, sample growth, and measurements. LÄS MER

  5. 4. Heterostructure Diodes for Millimeter Wave Power Generation

    Författare :Hans Grönqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single barrier varactor diode; AlSb barrier; InAs substrate; high frequencies; Resonant Tunneling Diode;

    Sammanfattning : This thesis deals with two types of heterostructure diodes namely the Resonant Tunneling Diode (RTD) and the Single barrier varactor diode (SBV). The RTD is a device for high frequency generation either as a negative reistance oscillators or as a multiplier. Different means to reach high frequencies are outlined. LÄS MER

  7. 5. Theoretical modeling of bipolar double-barrier resonant-tunneling light emitting diodes

    Författare :Anders Kindlihagen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is about firms determined to gain competitive advantages from environmental demands, about the efforts of engineers employed with the challenge of fulfilling environmental performance targets and about the management and organisation of product development. It is about incremental change, built on established technological knowledge, as well as about radical technological change. LÄS MER
