    Sammanfattning : In the field of sensing in general and biosensing in particular, there is a growing need for integratingminiaturised senor elements in microfluidic systems. The advantages are several, some of which being that the consumption of, often very expensive, sample material can be reduced; sampleexchange can be optimized; sensor performance in terms of detection limits can be improved and phenomena occurring on a very small, and even single-molecule, scale can be studied.

  4. 18. Studies of structural transitions in trimetal pentoxides of titanium and vanadium : from the growth of pure single-crystals to critical phenomena at the transition points

    Författare :Sam-Hyo Hong; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The growth of highly pure single crystals of titanium (Ti2O3-TiO2) and vanadium (V203-V205) oxides by chemical transport reactions with TeCl4 as a transport medium is discussed. The chemical transport mechanisms, transport rates and oxidation states of the transported crystals in the titanium and vanadium oxide systems are compared. LÄS MER

  5. 19. Revealing Electronic Structures of 2D Molecular Crystals and Correlating Them with Optoelectronic Properties

    Författare :Qingqing Wang; Mats Fahlman; Xianjie Liu; Heiko Peisert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2D molecular crystals; Crystal engineering; Electronic structure; Organic field effect transistors;

    Sammanfattning : Electronic band structure serves as the foundation for understanding the physics of semiconductors. The electronic band structure of inorganic semiconductors has been well understood based on ideal single crystal samples, thus actually laid the foundation for the prospering development of inorganic semiconductor devices.
