2. 1. Symmetrical FET Modeling

   Author : Ankur Prasad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; switch model; symmetrical model; nonlinear model; small-signal model; GaAs; Microwave FET; GaN;

   Abstract : This thesis deals with empirical modeling of symmetrical Field-Effect Transistors (FETs). It covers three distinct topics within the areas of modeling and parameter extraction of microwave FETs.First, the symmetry of FET devices is addressed. Such devices are often used in transceivers as a building block for switches. READ MORE

4. 2. Blue copper proteins as bioelements for bioelectronic devices

   Author : Olga Aleksejeva; Malmö universitet; []
   Keywords : Blue copper protein; Multicopper oxidase; Direct electron transfer; Oxygen bioelectroreduction; Enzymatic fuel cell; Biosupercapacitor;

   Abstract : This thesis is focused on bioelements for biological electric power sources,specifically, on blue copper proteins with and without an intrinsic biocatalyticactivity, i.e. ability to reduce oxygen directly to water. These proteins, viz. READ MORE

5. 3. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

   Author : Rohit Chandra; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

   Abstract : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. READ MORE

6. 4. Nanocellulose and Polypyrrole Composites for Electrical Energy Storage

   Author : Gustav Nyström; Maria Strömme; Leif Nyholm; Petr Novák; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; conducting polymer; polypyrrole; cellulose; nanocellulose; porosity; composite; energy storage; battery; supercapacitor; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Abstract : To meet the predicted increase in demand for energy storage in tomorrow's society, the development of inexpensive, flexible, lightweight and sustainable energy-storage materials is essential. In this respect, devices based on electroactive organic molecules, such as conducting polymers, are highly interesting. READ MORE

7. 5. 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.
