Profile Jordan AndrewsResearch Topic: Optical Functions for Gallium Arsenide Bismuth Semiconductor Alloys

Research Location: AMPEL

Research Supervisor: Dr. Stephen O'Leary

Research Description:

The semiconductor alloy, GaAsBi, has become a focus of attention due to its interesting
material properties and its potential for electronic and optoelectronic devices. It is found that the energy gap associated with this material diminishes rapidly in response to the introduction of relatively small amounts of bismuth. The aim of my analysis is to determine the optical functions associated with GaAsBi alloys. Identifying how these optical functions depend on the bismuth content will be a key goal. The material physics and device implications will also be examined.

Home town: Grand Forks, BC

Country:  Canada

Faculty/School:  Faculty of Applied Science

Program: Master of Applied Science

Why did you decide to pursue a graduate degree?

Choosing to stop my education after a Bachelors degree never felt like an option to me. I have
always had a passion for physics and engineering, constantly wanting to learn more. The
prospect of doing new research to contribute to a field is too exciting of an opportunity to pass

Why did you decide to study at UBC's Okanagan campus?

I spent four years completing my undergraduate degree on this campus and it was a fantastic
experience.  The campus is beautiful and the people are friendly. During my time here, I met
Dr. Stephen O'Leary in the School of Engineering who I have had many discussions with about
pursuing graduate studies, so staying on the campus was a natural choice.

What impact do you hope your research will have?

The dramatic reduction in the energy gap has pointed to the potential of GaAsBi for
long-wave length optoelectronic device applications. The low energy gap offered also suggest
that it might be a useful material for solar cell device applications. By adding additional
junctions in existing cells, additional regions of the solar spectrum can be absorbed, increasing
the efficiencies of solar cells. I hope that understanding the optical functions of this
semiconductor alloy can help to further device applications in these fields.
