Good, but 2 complaints:
Clays and glass are not just -different forms of SiO2-. They contain other elements besides silicon and oxygen, and it is because of those elements that they have different silicon-oxygen networks.
Molten quartz solidifies into an amorphous glass unless it is cooled very slowly. While crystalline quartz melts at 1713C, silica glass (called -fused quartz-) begins to soften at 1665C.

some people complain about these crash course chemistry vids because they are too fast, and have to pause/rewind.
I have to pause them to laugh and rewind over what I laughed through! the hand with the clay and the -ahh- sound, killed me. such comedic gold. relatively low brow, at the same time high brow. love it. thanks.

could a small piece of safe radioactive material like americium found in smoke detectors be used to knock the silicon atoms into the hole to make current flow? could use magnetic induction to increase the voltage and replace the battery in my phone. it wouldn-t need to be charged for 430years -

Wait, n-type semiconductors do not have negative charge, they have negative charge- carriers. there is a difference
The same is true for the p-type, the p-type silicon is not more positively charged than pure silicon, the charge in both cases is the same- neutral

well this is a very informational video, i don't really learn anything with CrashCourse. if I really cared about learning this (which I do) this isn't where I go to understand. it seems like their trying to cram for a test due in 20 minuets.

Hank! Since the most silicon is found in silicate rocks the silicon is bonded to oxygen forming SiO2 so oxygen is the most abundant element in the earth's crust. Maybe there should be a Crash Course Geology to teach this stuff.

You know you are a millennial if you grew up with modeling clay HaHaHa!
We use to play in the sand basically all day and sometimes have a nice snack haha

A description of a diode's operation without mentioning the depletion region is not much of a description and very misleading.

Steve mold does an amazing job at explaining this more detail if anyone wants to delve deeper. his video is how LED's work.

I was studying for my chemistry test, and I end up this video. I learned something more about my geology major! Thank you!
