  1. 1. Theoretical Studies of Diamond for Electronic Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Shuainan Zhao; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diamond; Surface functionalization; Electronic structure; graphene; dopant; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Diamond has since many years been applied in electronic fields due to its extraordinary properties. Substitutional dopants and surface functionalization have also been introduced in order to improve the electrochemical properties. READ MORE

  2. 2. Dopant diffusion in Si and SiGe

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Jens S. Christensen; KTH.; [2004]
    Keywords : condensed matter;

    Abstract : Dopant diffusion in semiconductors is an interestingphenomenon from both technological and scientific points ofview. Firstly, dopant diffusion is taking place during most ofthe steps in electronic device fabrication and, secondly,diffusion is related to fundamental properties of thesemiconductor, often controlled by intrinsic point defects:self-interstitials and vacancies.

    Abstract : Organic semiconductors may enable a wide range of flexible electronics, such as flexible displays or solar cells. Conjugated polymers constitute one of the most widely studied class of organic semiconductors. READ MORE

  4. 4. SiGeC Heterojunction Bipolar Transistors

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Erdal Suvar; KTH.; [2003]
    Keywords : Silicon-Germanium-Carbon SiGeC ; Heterojunction bipolar transistor HBT ; chemical vapor deposition CVD ; selective epitaxy; non-selective epitaxy; collector design; high-frequency measurement; dopant segregation; thermal stability;

    Abstract : Heterojunction bipolar transistors (HBT) based on SiGeC havebeen investigated. Two high-frequency architectures have beendesigned, fabricated and characterized. Different collectordesigns were applied either by using selective epitaxial growthdoped with phosphorous or by non-selective epitaxial growthdoped with arsenic. READ MORE

  5. 5. Advanced TCAD Simulations and Characterization of Semiconductor Devices

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tony Ewert; Uppsala universitet.; [2006]
    Keywords : Electronics; MOSFET; RDF; random dopant fluctuation; asymmetric; parametric mismatch; TCAD; compact modeling; fluctuation model; Elektronik;

    Abstract : Today, micro- and nano-electronic devices are becoming more complex and advanced as the dimensions are shrinking. It is therefore a very challenging task to develop new device technologies with performance that can be predicted. READ MORE
