2. 1. Crack-junctions : Bridging the gap between nano electronics and giga manufacturing

   Author : Valentin Dubois; Göran Stemme; Christofer Hierold; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; nanoelectronics; nanogap electrodes; molecular electronics; nanoplasmonics; crack-junctions; break junctions; nanowires; parallel fabrication; lithography; fracture; crack; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Obtaining both nanometer precision of patterning and parallel fabrication on wafer-scale is currently not possible in conventional fabrication schemes. Just as we are looking beyond semiconductor technologies for next-generation electronics and photonics, our efforts turn to new ways of producing electronic and photonic interfaces with the nanoscale.

5. 3. Photochemical and Photoelectric Applications of II-VI Semiconductor Nanomaterials

   Author : Abhilash Sugunan; Mamoun Muhammed; Lars Kloo; KTH; []
   Keywords : ZnO; Nanowire arrays; Photocatalysis; Nanofibers; CdTe; Nanotetrapods; Ostwalds ripening; Photoconduction; Nano-gap electrodes;

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

6. 4. Theoretical studies of a nanoparticle bridge platform for molecular electronics measurements

   Author : Henrik Löfås; Rajeev Ahuja; Jan Isberg; Anton Grigoriev; Gemma Solomon; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : The main focus of this thesis is the theoretical investigations of a nanogap platform used for molecular electronics measurements under ambient conditions. The nanogap is about 20 nm wide, while the molecules investigated here (octanethiol(OT) and octanedithiol(ODT)) are about 1-1.5 nm long making it impossible to bridge the gap with one molecule.
