  1. 1. Resistivity and the solid-to-liquid transition in high-temperature superconductors

    University dissertation from Stockholm : KTH

    Author : Beatriz Espinosa Arronte; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-temperature superconductors; vortex dynamics; vortex solid-to-liquid transition; critical scaling; glass transition; Bose glass; heavy-ion irradiation; YBCO; Tl2Ba2CaCu2O8 d; oxygen deficiency.; NATURAL SCIENCES Physics Condensed matter physics; NATURVETENSKAP Fysik Kondenserade materiens fysik;

    Abstract : In high-temperature superconductors a large region of the magnetic phase diagram is occupied by a vortex phase that displays a number of exciting phenomena. At low temperatures, vortices form a truly superconducting solid phase which at high temperatures turns into a dissipative vortex liquid. READ MORE

  2. 2. Nanopatterning by Swift Heavy Ions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marek Skupinski; Uppsala universitet.; [2006]
    Keywords : Materials science; swift heavy ions; lithography; nanopatterning; self-assembly; Materialvetenskap;

    Abstract : Today, the dominating way of patterning nanosystems is by irradiation-based lithography (e-beam, DUV, EUV, and ions). Compared to the other irradiations, ion tracks created by swift heavy ions in matter give the highest contrast, and its inelastic scattering facilitate minute widening and high aspect ratios (up to several thousands).

  3. 3. Stability of point defects in silicon induced by high energy low dose ion implantation

    University dissertation from Institutionen för elektronisk systemkonstruktion

    Author : Lalita Josyula; KTH.; [1997]
    Keywords : ;

    Abstract : Ion implantation is a key' process for the introduction ofdopants in semiconductor technology. It involves bombarding thesubstrate material with energetic ions. READ MORE
