Diode Definition and 555 Threads

The problem is an experiment has to be set up to investigate how the breakdown voltage (which occurs by a large reverse potential difference is applied to the diode, and the diode then passes a large current) of a semiconductor diode is affected by temperature. My problem is how can I vary...

Sketch the output voltage as a function of time. The AC voltage source is V_{o}cos(\omega)t with V_{o} = 10V and \omega = 2000rad/sec. I have posted a diode circuit question in the attachment Ok, I think it should be a sine curve with a 10 V amplitude but am not too sure about the period...

has anyone come across any website with good information on OLED technology. I'm not really looking for the technical details. What I?m interested in is a general overview of the technology. What it is advantage/disadvantages , applications, history. Stuff like that. i would really...

If you put a diode in circuit with a piece of metal, heat the metal so the electrons start jiggling about the diode should let only the elctrons going in a certain direction through thus creating a small current. I read somewhere this does not work but it did not explain why, or does it work in...

How does a diode work? Or more precicely how does a semiconductor such as silicon only allow current to flow one way around a circuit?
