Summer Chemistry Research
July 9, 2009
Samantha DeCarlo '10 and Heather Sheridan '10 are working in Dr. Marteel-Parrish's research lab for the second time this summer. Research took a different turn when development of thin films in the semiconductor industry became a hot topic!

First step of the synthesis: making of acidic solution of titanium oxide.
Adding the acidic solution to the barium mixture.
Checking the temperature of sand bath.
Securing everything!
Samantha is characterizing her intermediate using our new Nuclear Magnetic Spectrometer. This is our state-of-the-art big magnet!
The final solution is under reflux conditions for 8 hours.
Mirror, mirror, what do you see??? Heather Sheridan's face is reflected in a silicon wafer, substrate on which layers of semiconductors are deposited and a thin film is ultimately formed.
The first step in the deposition process.
Our first layer on our silicon wafer!
Let's see what the microscope can reveal!
Anything interesting, Heather?
Research took another turn when the challenge of obtaining crystals from a powder material came along!
Transfer in a porcelain crucible before cooking in a tube furnace.
The porcelain crucible is getting a warm up!
Heather is making sure the crucible is in place.
Can you guess whose eye is it?
What about this one?

Time to take a break!!! Dr. M.-P. and Heather.
Two happy women: Dr. M.-P. and Samantha.
