  1. 6. Electrical and Optical Characterization of InAsP/InP Nanowire-Based Avalanche Photodetectors

    University essay from Högskolan i Halmstad/Fotonik

    Author : Praveen Kumar Singaravelu; Tawhidul Alam Mohammad; [2016]
    Keywords : ;

    Abstract : The availability of new manufacturing methodology in solid state physics makes it possible to grow nano-photonic devices for better performance and unique properties. In this thesis work, we use I-V and FTIR spectroscopy to study the electrical and optical properties of InAsP/InP nanowire-based array avalanche photodetectors for near infrared applications.

  5. 9. Electro-optical Characterization of Semiconductor Nanowire Devices

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

    Author : Neimantas Vainorius; [2012]
    Keywords : Nanowire; InP LED; differently doped InP FETs; GaSb InAsSb InAs photodetectors; Fourier transform spectroscopy.; Physics and Astronomy;

    Abstract : Degradation of properties of semiconductor devices when layers of different materials are grown on top of each other is a common issue if their lattices are mismatched. Strain between them is reduced by creating defects like vacancies. This problem can be solved by growing structures, called nanowires, where stress is reduced radially. READ MORE
