    Selectivity of isophorone diisocyanate in the urethane reaction influence of temperature, catalysis, and reaction partners

    In a model study of the selectivity of isophorone diisocyanate (IPDI) in the urethane reaction, the influence of the type of catalyst, temperature, and type of OH-group was demonstrated using primary and secon...

    The sites and dynamics of p-xylene guest molecules in Dianin’s inclusion compound; a deuteron NMR study

    Single crystals of Dianin’s inclusion compound with methyl and ring deuterated p-xylene guest molecules were grown and studied by FT deuteron NMR. The spectra from the deuterated methyl groups reveal that thes...

    Fabrication of Ultrasmall InGaAs/InP Nanostructures by High Voltage Electron Beam Lithography and Wet Chemical Etching

    We have fabricated high quality In0.53Ga0.47As/InP quantum wires by high voltage electron beam lithography and wet chemical etching. Lateral dimensions of the wires down to 16 nm have been achieved. The wires sho...

    Luminescence Study of Wet Chemically Etched InP/InGaAs-Submicron-Structures

    We have investigated the optical properties of wet chemically etched InP/InGaAs-wires and dots with widths between 100 nm and 10 µm for different excitation densities. We observe that the non radiative recombinat...

    Selective growth of InP in the low pressure hydride VPE system

    We have investigated the selective growth of InP in a low pressure hydride VPE system. Although the system operates further from thermodynamical equilibrium than the atmospheric pressure VPE system, high selec...
