Assuming a built in voltage equal to the bandgap voltage, calculate the slowest possible transmit time for a carrier with 5V reverse bias applied to the GaAs photodiode.

I would be able to do this problem without difficulty if it wasnt for the part mentioning "Bandgap Voltage." I am familiar with bangap energy and how to calculate it, but I have no idea how to figure out the bandgap voltage for a given material. Can anyone give me any hints on this?

Thanks!
