  1. 11. In situ X-ray diffraction studies of vertically aligned CsPbBr3 nanowire arrays

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Jesper Larsson; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.

  3. 12. Thermoelectric measurements on InAs nanowires with a ratchet-barrier

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

    Author : Hanna Lundström; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.

  4. 13. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofie Johannesson; Sebastian Skog; [2022]
    Keywords : Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

    Abstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

  5. 14. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rungeng Xu; [2022]
    Keywords : E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

    Abstract : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. READ MORE

  6. 15. Investigating the use of Semiconductor Nanowires for Neural Networks

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alfredo Serafini; [2022]
    Keywords : FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

    Abstract : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. READ MORE
