2. 1. III–V Nanowire Surfaces

   Author : Martin Hjort; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; low energy electron microscopy; scanning tunneling spectroscopy; scanning tunneling microscopy; surface; III–V semiconductor materials; nanowire; photoemission electron microscopy; photoelectron spectroscopy; Fysicumarkivet A:2014:Hjort;

   Abstract : This dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS).

4. 2. Vertical Heterostructure III-V MOSFETs for CMOS, RF and Memory Applications

   Author : Adam Jönsson; Nanoelektronik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; CMOS; RRAM; III-V; InAs; GaSb; InGaAs; Heterostructure; vertical; nanowire NW ; MOSFET; III-V materials; RRAM; RF; CMOS; InAs; GaSb; InGaAs; heterostructure; Vertical nanowire;

   Abstract : This thesis focuses mainly on the co-integration of vertical nanowiren-type InAs and p-type GaSb MOSFETs on Si (Paper I & II), whereMOVPE grown vertical InAs-GaSb heterostructure nanowires areused for realizing monolithically integrated and co-processed all-III-V CMOS.Utilizing a bottom-up approach based on MOVPE grown nanowires enablesdesign flexibilities, such as in-situ doping and heterostructure formation,which serves to reduce the amount of mask steps during fabrication.

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

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

   Abstract : 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.
