2012 High school women interns, from
left to right: Asia Cunningham, Carly
Green, Jessica Greer, Jasneet Singh, and
Katelyn Lennon following the end-ofsummer presentation of their research
results. Second row left to right: Ohio
State Prof. Leonard Brillson, Columbus
School for Girls’ science teacher and
liaison Dr. Kevin Sweeney, and Ms.
Jemma Giddings, CSG Upper School
Director.
Ms. Jasneet Singh ,a rising high school
senior, and postdoc Snjezana “Snow” Balaz
working in Prof. Brillson’s lab with an ultra
high vacuum chamber, glancing incidence
electron gun, and monochromator for
DRCLS . Jasneet and Snow measured the
type and depth of native point defects
within the outer few atomic layers of oxide
single crystals. They found major growth –
dependent differences in the type of
native point defects in the ZnO and SrTiO3
substrates used to grow most complex
oxides. These defects then strongly
influence interface electrical
measurements.
2011 High school women interns, Adele
Anderson, Audrey Coble, Lauren Gerber,
Judith Keys, and Grace Bowen following
the end-of-summer presentation of their
research results. Second row: Ohio State
Profs. Umit Ozkan, Leonard Brillson,
Stephen Lee, Columbus School for Girls’
science teacher Dr. Kevin Sweeney and
Prof. John Lannutti.
Ms. Meghna Srikanth, a rising high school
junior, and postdoc Snjezana “Snow”
Balaz working in Prof. Brillson’s lab with an
ultra high vacuum chamber, glancing
incidence electron gun, and
monochromator for depth-resolved
cathodoluminescence spectroscopy
(DRCLS). Audrey and Snow measured the
depth distribution of native point defects
within the outer few atomic layers of
electronic oxide single crystals. These
nanoscale measurements revealed a huge
sub-surface accumulation of native point
defects whose type depended on the
crystal’s surface orientation.
2010 High school women interns Meghna
Srikanth, Mary Muigai, Margaret Yatsko,
and Sarah Shaffer following the end-ofsummer presentation of their research
results. Second row: Ohio State Profs.
Leonard Brillson, Stephen Lee, John
Lannutti, and Columbus School for Girls’
science teacher Dr. Kevin Sweeney
Ms. Meghna Srikanth, a rising high school
senior, working in Prof. Brillson’s lab with an
ultra high vacuum chamber for depth-resolved
cathodo-luminescence spectroscopy (DRCLS).
The AFM enabled Meghna, postdoctoral fellow
Snjezana Balaz, and graduate student Daniel
Doutt to measure native point defects within the
outer few atomic layers of ZnO single crystals.
These nanoscale measurements revealed a
striking correlation between zinc vacancies
observed via DRCLS and surface photovoltage
spectroscopy.
2009 High school women
interns Laura Arnold,
Elizabeth Hubler, Mary
Mugai, and Margaret
Yatsko, following the endof-summer presentation of
their research results.
Second row: Ohio State
Prof. Leonard Brillson and
Columbus School for Girls’
science teacher Dr. Kevin
Sweeney.
Ms. Elizabeth Hubler, a rising
high school senior, working in
Prof. Brillson’s lab with an
atomic force microscope
mounted in a vibration isolation
enclosure. The AFM enabled
Elizabeth, graduate student
Daniel Doutt, and REU student
Tyler Merz to measure surface
morphology, work function, and
surface photovoltage
spectroscopy of ZnO
nanostructures. In turn, these
nanoscale measurements have
revealed an atomic mechanism
by which nanorods grow
spontaneously in air.
2008 High school women interns Dina
Tayim, Laura Arnold, Anyssa Armstead and
Margaret Yatsko, following the end-ofsummer presentation of their research
results. Ohio State University President
Gordon Gee (center) made a surprise visit
rd
in honor of the program’s 3 year and
continuing success. Dr. Kevin Sweeney of
Columbus School for Girls is at far right.
Ms. Michelle Myers née Kramer in 1997
taking current-voltage measurements at a
probe station for 2 journal articles on ZnO
Schottky barrier formation. Ms. Kramer is
now working toward her Ph.D. in Physics at
Texas A&M. She recently wrote: “I wanted to
thank you for your inspiration to study solid
state electronics in graduate school. I find
that I am just as excited about it now as I
was when I finished my research
assistantship with you. The experience was
truly worthwhile and I am eternally grateful
for the opportunity.”
