Thanks for the reply.
You're right, rectifying characteristics means it allows current to flow in one direction, and blocks in the other. Which clears that up at least, and explains why you want ohmic contacts.
The research is progressing anyway haha ...I am writing an interim...
Hey, thanks for the reply.
I am trying to research reducing the barrier height in transistors. From what I have been reading it says that when the metal and semiconductor for a pn junction, the contact can have a Schottky barrier which exhibits rectifying characteristics.
I may have this...
A Schottky barrier is said to have rectifying characteristics, which from what I can understand is bad ...but would the rectifying characteristics mean that current passing through the junction would be flat ....level is probably a better way to describe it rather than flat.
Ah sorry. I meant voltage into the USB. I obviously didn't pay too much attention to what I was writing. Sorry.
So, I take it there is a regulator on the input to the USB, which will take it down to the required spec?
This is probably a silly question. But it is something I haven't been able to find an answer too.
When I connect something to my laptop through the USB, I know that there is 5V coming from the USB connection ...there are many pinout diagrams about that show this. But what is the...
In a class today, the lecturer said, in an introduction to the material that will be covered, something along the lines of "..and the current is kept relatively flat (low?) thanks to impedance ..."
Is this because impedance acts like resistance (but in AC circuits), or would there be...
