Postovane koleginice i kolege,
U periodu od 14. do 18. novembra 2005. godine u Beogradu ce,
kao gost Univerziteta, boraviti Prof. Josef Pelzl, Institut
für Experimentalphysik, Ruhr-Universität, Bochum, Germany.
U okviru svog boravka Prof. Pelzl ce imati i dva interesantna
predavanja, pa vas pozivamo da ih i posetite.
Prvo predavanje je u utorak 15. novembra 2005. sa pocetkom u
18.00 h u sali za konferencije hotela „PARK“ u Beogradu, pod
naslovom
"Investigation
of nano-structured semiconductor, magnetic and mechanical devices by thermal
wave based microscopy"

Abstract: Thermal
wave based scanning probe techniques have been used to control the thermal
management of devices and to image material properties on microscopic scales
such as the thermal parameters and local magnetic characteristics. A novel
combined scanning thermal and scanning thermal expansion microscope has been
applied complemented by finite element simulations to determine the local
temperature of hot spots in semiconductor devices. Thermal and thermo-elastic
response of the microwave resonance has successful been applied for magnetic
imaging. Using the scanning thermal ferromagnetic resonance microscopes it was
possible to image the microwave resonance absorption of a Permalloy stripe and
of a Ninano-dot. Monitoring the thermal response at a multiple frequency of an
ac-heated thermal probe the thermal conductivity on nano-scale can be
controlled. A revised analytical approach of this method has been developed and
applied successfully to nano-structured shape memory alloy devices.
Ovo predavanje je u sklopu 1st International
Workshop on Nanosciences 2005.
Drugo predavanje planirano je za sredu 16. novembar u 12.00
h na Fakultetu za fizicku hemiju Univerziteta u Beogradu, na I spratu, soba 445
pod naslovom
“Photothermal
Materials Characterisation”
J. Pelzl
Abstract: Photothermal
methods rely on the detection of the heat originating from non-radiative decay
of the electronic and vibrational states. Detection of the heat diffusion
governed signals allows depth profiling of optical, magnetic and thermal
properties which is widely applied in materials research. Due to the absence of
photon noise the prompt heat response is very suitable for trace detection in
gases, liquids and solid matter. Applications also from other groups in
environmental, medical and food science will be briefly reported.
Pored tih predavanja, Prof. Pelzl ce
u cetvrtak, 17. novembra 2005, u periodu od 11.00 do 15.00 biti gost Laboratorije
za atomsku, molekulsku i lasersku spektroskopiju Instituta za fiziku u Zemunu. Tokom
svoje posete Institutu planiran je obilazak vise laboratorija i upoznavanje sa delom
domacih i medjunarodnih projekata koji se tu rade.
Za blize informacije u vezi posete Prof.
Pelzl-a mozete se obratiti na adresu markusev@phy.bg.ac.yu
Srdacan pozdrav
