Re: General Thoughts: Physics

But shouldn't it have the lowest energy gap to be efficient ?
nope it should have the gap that corresponds to the predominant energy of the light. still not sure if my answer is correct though. anyone have confirmation?

Re: General Thoughts: Physics

I had 5c. Gallium is group III. What'd you guys think of 6. I initially had C, but changed it to A; due to the fact it changed from -1 to -2, so why do the field lines double as well?

And yeh I had 20 b as well.
