  5. 4. Nanowire Transistors and RF Circuits for Low-Power Applications

    Författare :Karl-Magnus Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :InAs; Nanowire; Metal-oxide-semiconductor field-effect transistor; MOSFET; RF; Mixer; Circuit; 1 f-noise; Simulation; Modelling;

    Sammanfattning : The background of this thesis is related to the steadily increasing demand of higher bandwidth and lower power consumption for transmitting data. The work aims at demonstrating how new types of structures, at the nanoscale, combined with what is referred to as exotic materials, can help benefit in electronics by lowering the consumed power, possibly by an order of magnitude, compared to the industry standard, silicon (Si), used today.
