  2. 11. Green Chemical Synthesis of II-VI Semiconductor Quantum Dots

    Author : Robina Shahid; Mamoun Muhammed; Gunnar Westin; KTH; []
    Keywords : Semiconductor; Quantum Dots; Microwave; Ionic Liquids; Green Chemical Syntheis; Quantum Confinement; Optical Properties;

    Abstract : Nanotechnology is the science and technology of manipulating materials at atomic and molecular scale with properties different from bulk. Semiconductor QDs are important class of nanomaterials with unique physical and chemical properties owing to the quantum confinement effect. READ MORE

  4. 12. Fabrication and Photoelectrochemical Applications of II-VI Semiconductor Nanomaterials

    Author : Abhilash Sugunan; Muhammet Toprak; Mamoun Muhammed; Gerrit Boschloo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; nanowire arrays; photocatalysis; CdTe; CdSe; CdS; nanotetrapods; nanotetrahedrons; photoconduction; nano-gap electrodes; Type-II QDs; P3HT nanofibers; microwave synthesis.;

    Abstract : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdE (E=Te,Se,S) quantum structures synthesized by solution-based thermal decomposition of organo-metallic precursors.
