4.7 COLLABORATIVE RESEARCH
University Nacional del Litoral, Argentina
Prof. Roman Buitrago from the University Nacional del Litoral in Santa Fe, Argentina, visited
the Centre for three months from August to November 2005. He was principally involved in
work on solid-phase crystallisation of evaporated amorphous silicon, but also provided useful
contributions to other areas of Second Generation Strand activities.
Materials Science and Engineering, UNSW
A very successful collaboration was initiated with Dr Yu Wang, Materials Science and
Engineering, UNSW. Dr Wang contributed signifi cantly to another trip to the Photon Factory
synchrotron facility at Tsukuba, Japan in December 2005. This trip was funded by AINSE
under the Australian Nuclear Beamline Facility project. Dr Wang has also provided facilities
and expertise for X-ray tube X-ray diffraction. The result of both these experiments has been
very useful and has provided complementary structural information from X-ray diffraction on
the silicon quantum dot nanostructure work.
Aachen University, Germany
A collaboration was established with Dr Andreas Nositschka and Robert Rolver at Aachen
University on time resolved photoluminescence. Initial data on PL on Si nanostructure
samples was very promising. This will be built upon to develop time resolved data which
should elucidate decay mechanisms in the material.
Rudjer Boskovic Institute, Zagreb, Croatia
Dr Branco Pivac and Ivana Kovačević from Zagreb carried out Grazing Incidence Small Angle
X-ray Scattering (GISAXS) measurements on Si nanostructure samples at the synchrotron
facility in Trieste. This gave information on nanocrystal size which complemented TEM data
on the same samples and also gave information on nanocrystal shape – confi rming that they
are spherical.
Fraunhofer-Institute for Solar Energy Systems, Freiburg, Germany
University of Bern, Switzerland
Collaboration has continued on the Up/Down conversion project, see Up/Down-conversion in
Third Generation Strand section. H.U. Güdel and K. Krämer from Bern have provided further
Er doped phosphors and helped to interpret results of absorption and PL measurments. S.
Glunz from ISE, has again provided some of the bifacial cells used in the Up-conversion device
experiments.
School of Physics, University of Sydney
Further collaboration has been established with Dr Nicholas Ekin-Daukes at Sydney University
targetting carrier cooling measurements using a femtosecond pulsed laser, which is soon
to be established. This is part of a successful LIEF proposal which also included pulsed DC
sputtering with Prof. Marcella Bilek at Sydney and pulsed laser deposition with Dr Nagy
Valanoor at UNSW.
