MENTOR: CEDRIK MEIER (the German sensation)
PROFESSOR: EVELYN HU, PhD

My research dealt with photonic crystals. Photonic crystals are small pieces of semi-conductors (in my case gallium arsenide) with periodic holes in them. In the center of the photonic crystal is a defect, a spot where there should be a hole but none exists. Light is emitted from this spot with very high intensity. This is known to be true. However, I used the focused ion beam to make a flap that put the cavity at an angle and tested whether or not it still emitted light, a new experiment.

In the Lab...

Here I, along with my mentor Cedrik, am using the FIB (focused ion beam). This machine has both an SEM (scanning electron microscope) and a gun that shoots ions at the sample. I used this machine to take pictures of my sample as well as cut that flaps on the photonic crystals.

Here I am in the micro-PL (photo-luminescent) lab. This is where I gathered the data that told me how strong the light emitted from the photonic crystals was.
