RAMAN SPECTROSCOPY OF NANOSTRUCTURES
POST DOCTORAL POSITION, PHOTONICS GROUP,
UNIVERSITY OF TORONTO
A post doctoral position is available at the University of Toronto,
Department of Electrical and Computer Engineering for a 1 year term. This
term is subject to extension. The Department consistently ranks among the top
10 in North America. It attracts outstanding students, has excellent research
and teaching facilities, and is ideally located in the middle of a vibrant
cosmopolitan city.
The scope of the position is Raman spectroscopy of nanostructures. Quantum
confined nanostructures such as quantum wires, short superlattice structures
and quantum dots are the core focus of this research. The vibrational modes of
these structures include not only those representing the bulk from which the
structures are made, but also other modes pertinent to the phonon
confinement in the nanostructures. Raman and PL Measurement facilities are
already in place but some instrumentation development may be involved.
Specifically, zone-folded acoustic phonons, confined optical phonons, and
electrostatic interface modes will be used to characterize the properties of
nanostructures. While the physics of these modes is interesting, they can also
be utilized as a sensitive tool for probing the structure, disorder, stress, size
dispersion, and core-shell properties of nanostructures. Rigorous
understanding of these nanostructures characteristics may hold the key to
enhancing the control we have over their properties.
Raman spectroscopy is particularly suited for coupling the studies mentioned
above with the performance of numerous devices produced using these
nanostructures. Devices encompassed in this work will include efficient
detectors, light emitters and nonlinear optical elements.
Candidates with doctoral degrees in physics, applied physics, electrical
engineering or any related discipline will be considered. The post encompasses
a strong experimental component. Hence a previous experience in optical
spectroscopy or related disciplines is preferred. The successful candidate is
expected to interact strongly with graduate students, post doctoral fellows and
numerous collaborators from around the world. Team work and interpersonal
skills are therefore essential.
