1. 1. Determining the voltage range of a carbon-based supercapacitor

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Thomas Wells; [2014]
   Keywords : Carbon electrodes; aqueous electrolytes; sodium sulphate; lithium sulphate; super capacitor; EDLC; electrochemical double layer capacitor; EDL; graphite; nano porous;

   Abstract : The focus of this thesis has been to determine the usable voltage range of carbon-based supercapacitors (SC). Supercapacitors are a relatively new type of capacitors with a vast increase in capacitance compared to capacitors which utilize a dielectric as charge separator. A SC consists of two electrodes and an electrolyte separating the electrodes. READ MORE

3. 2. Polyelectrolyte based organic field effect transistors

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Fareed Mohammad Ahmed; [2007]
   Keywords : ;

   Abstract : In this thesis work, the fabrication of dual gate organic field-effect transistors (DGOFETs) using polyanionic proton conductor named polyvinylphosphonic acid and acrylic acid P(VPA-AA), SiO 2 as gate insulating materials and poly(3-hexylthiophene) (P3HT) as organic semiconductor have been studied. Upon operation, the top insulating layer forms large electric double layer capacitors (EDLCs)at the Ti/P(VPA-AA) and P(VPAAA)/ P3HT interfaces. READ MORE
