  1. 1. Modelling Graphene Field-Effect Transistors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sofia Sjölander; [2017]
    Nyckelord :Graphene; FET; GFET; Field Effect-transistor; QMUL; Technology and Engineering;

    Sammanfattning : Today, transistors with 20 nanometer (nm) channel length are in mass production and many researchers believe that we are reaching a limit with downsizing conventionally used silicon metal-oxide-semiconductor field-effect transistors (MOSFETs) [1]. To keep up with the trend of making the transistor smaller, new channel materials are studied, and graphene has come into the spotlight. LÄS MER

  3. 2. Electrical Characterizationon Commercially Available Chemical Vapor Deposition (CVD) Graphene

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mikael Anttila-Eriksson; [2016]
    Nyckelord :GFET; Graphene; Dirac point shift; Charge carrier mobility;

    Sammanfattning : Field-effect transistors (FET) based on graphene as channel has extraordinaryproperties in terms of charge mobility, charge carrier density etc. However, there aremany challenges to graphene based FET due to the fact graphene is a monolayer ofatoms in 2-dimentional space that is strongly influenced by the operating conditions.

  4. 3. Fabrication and Characterization of Tunneling Oxides on Graphene

    Master-uppsats, KTH/Mikroelektronik och tillämpad fysik, MAP

    Författare :Melkamu Belete; [2013]
    Nyckelord :;

    Sammanfattning : Graphene base transistors (GBTs) are known to be novel devices mingling outstanding properties of graphene, with the concept of hot electron transistors (HETs). According to theoretical calculations, GBTs were predicted to have over 5 orders of magnitude ON/OFF current ratios and THz frequency range operations. LÄS MER
