I'm working with a sensing material and want to better understand its response. I have the theoritical elements worked out, but now want to begin testing and have no idea what type of tools/instrumentation would be required for the task.
What I'm testing:
- Two terminal device
- A photon interacting with this device creates a change in current (10-100nA).
- The signal generated from this interaction could last between 10-100ps (picoseconds).
My question is what is the instrumentation required to measure at such high speed (10-100ps) with such a small change in current (10-100nA)?
Thank you for your time. Cheers
