  2. 1. Functionalized Graphene as Superlattice and Gas Sensor

    Author : Tianbo Duan; Klaus Leifer; Andrey Turchanin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; graphene; functionalization; gas sensor; superlattice;

    Abstract : Graphene, an atomic-thin carbon sheet with carbon atoms tightly packed honeycomb-like lattice, has attracted enormous interest due to its unique chemical and physical properties. However, the intrinsic zero bandgap characteristic of graphene has so far prevented graphene from building effective electronic and optoelectronic devices. READ MORE

  4. 2. Graphene-based Devices for More than Moore Applications

    Author : Anderson Smith; Mikael Östling; Mihai Adrian Ionescu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Humidity Sensor; Pressure Sensor; GFET; CMOS; BEOL; More than Moore; Integration; Statistics;

    Abstract : Moore's law has defined the semiconductor industry for the past 50 years. Devices continue to become smaller and increasingly integrated into the world around us. Beginning with personal computers, devices have become integrated into watches, phones, cars, clothing and tablets among other things. READ MORE

    Abstract : Nowadays, electronic devices span a diverse pool of applications, especially when getting smaller and smaller satisfying the more than Moore paradigm. To further develop this, studies focusing on material design toward electronic devices are crucial. READ MORE

  6. 4. Biosensing platforms using graphene based bioreactive nanostructures with various dimensions

    Author : Yuanyuan Han; Klaus Leifer; Jöns Hilborn; Hu Li; Boukherroub Rabah; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; nanoparticles; nanostructure; biosensors;

    Abstract : Nanomaterials have brought new aspects and improvements to the biosensing field due to their unique physical and chemical properties that are not shown in the bulk state. This thesis focuses on concepting, developing and testing of biosensors where nanomaterials including graphene gold nanoparticles (AuNPs) and magnetic nanoparticles (MNPs) constitute the biosensors.
