  1. 6. EBL Patterned ITO Contacts for Single Nanowire Devices

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

    Author : Markus Snellman; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Nanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements.

  3. 7. Characterization of single InP Nanowire-based Avalanche Photodetectors

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

    Author : Virginia Boix De La Cruz; [2016]
    Keywords : Photodetectors; Nanotechnology; Nanowires; IndiumPhosphide; Semiconductors; Physics and Astronomy;

    Abstract : Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. READ MORE

  4. 8. STM-based characterization of single GaInP photovoltaic nanowires

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

    Author : Johannes Brask; [2016]
    Keywords : STM top contact method GaInP nanowire array solar cell; Physics and Astronomy;

    Abstract : The I-V and photovoltaic properties of III-V semiconducting GaInP nanowires have been studied using a scanning tunneling microscope (STM) in evaluation for usage as a potential "sub cell" in a nanowire based tandem solar cell configuration. This evaluation required precise I-V characterization and photo response measurements of individual nanowires. READ MORE

  5. 9. Vertical heterostructure III-V nanowire MOSFETs

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

    Author : Adam Jönsson; [2016]
    Keywords : MOSFET; transistor; heterostructure; III-V; RF; semiconductor; silicon; fabrication; electronics; Technology and Engineering;

    Abstract : If cars had developed as fast as processors they would go at 470,000 mph, get 100,000 miles to the gallon, and cost 3 cents" claims Paul Ottelini, Intel CEO 2005-2013. This serves as a reminder of how fast the field of nanoelectronics is developing due to constant demand for faster and more energy efficient integrated circuits. READ MORE

  6. 10. Electrical Properties of planar Metal-GdN-Metal junctions for Spintronic Applications

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

    Author : Felicia Ullstad; [2015]
    Keywords : nitride; gadolinium; spintronic; rare earth nitride; ferromagnetism; ferromagnetic; Semiconductor; Physics and Astronomy;

    Abstract : In this thesis the properties of planar metal-gadolinium nitride-metal junctions have been studied with the aim of establishing ohmic and Schottky contacts to thin polycrystalline films of n-type gadolinium nitride (GdN). GdN is an intrinsic ferromagnetic semiconductor of the rare earth nitride series. READ MORE
