Have you tried speaking with someone in your department?
What are you looking for--how many bedrooms, do you need in-unit laundry, how much do you want to spend? Would you consider having a roommate?
I would first try craigslist--not sure if I can post the link or not, but hopefully the mods will allow:
craigslist: raleigh / durham / CH classifieds for jobs, apartments, personals, for sale, services, community, and events (if the link gets cut and you're not familiar with craigslist, google "raleigh craigslist" There are lots of apartments listed there, and sublets, and even some house-sits.
good luck!
