If I'm reading you correctly, I think that's what I'm trying to say. Essentially, you're building a Schottky diode with an ideality factor far from 1.

I'm curious if Dreak's point answers your question. For wide-bandgap materials, as with any, the position of the Fermi level is highly dependent on how much activated dopant there is. Or is this too basic an explanation to address your question? Of course, the value of a nominally intrinsic...

I'm doubtful if that's the best model. It seems this application of Poisson's equation is somewhat arbitrarily set up. How do you have excess electrons? The electrons are supplied by the donor atoms, after all. If Nd is limited to a certain total number by the semiconductor volume, then...

According to medical physicists I've talked to, not only has their been better awareness of health concerns (you may remember <a href="http://gajitz.com/1950s-radioactive-science-kit-most-dangerous-toy-ever/"> this</a>), but also the technology for energy control, tight-beam collimating, signal...

It may also be helpful to remember that potential energy is entirely arbitrary. It doesn't matter what's in your snapshot of a system, all that matters is that you have a conservative force (e.g. gravity) and two points of reference. As a matter of fact, you could put the ball on the ground...

You're probably right. I do think it's a Pi network, so that second one might be parallel. I'll check when I get back to work in the morning, and if so, then let me know if I need to tweak the schematic for the viewers here to avoid confusion. As for the result, yes, I thought that would...

Greetings, I have shifted much of the focus of my research from thin film specifics to the plasma chamber we are using, as I was unfamiliar with the intricacies of plasma and found that a lot of the parameters we are counting on frankly could not be counted upon. I'm still green, but it's...

Related to the general topic, that would be my interpretation. There are a few ways to make that happen, such as a movable end to the enclosed container (think drum) or similarly an acoustic disturbance on a relatively rigid container, a temperature change, etc., but essentially you'd have a...

I'll throw my picture out there to the wolves (be gentle). Physically, without the use of equations, it may be helpful to visualize what is actually occurring to create the pressure in the first place. Pressure in fluids is just the sum of the change in momentum of all of the particles that...

I believe this is an important contribution. Most likely that website will also detail the difference between he eye's absorption mechanism of red and green light. Seeing red in the dark vs. light should not be substantially different since the eye's saturation to red light doesn't scale...
