I've been trying to understand this for the past week. You broke it down in 8 minutes. Fantastic explanation!

@MrSmithsPhysicsonline 4 года назад

Fantastic comment - thank you!

@florenckaf Год назад

I knew somewhere on youtube there must be a great explanation that's understandable, among all those other videos that aren't that. Now I found it. Thank you so much!

@MrSmithsPhysicsonline Год назад

What a nice comment - thank you very much! Glad you found it useful.

@stuthomas3593 3 года назад

Fantastic that you take the time to explain these topics to kids and parents alike... especially now with the dreaded home schooling, yes I'm a parent trying to stay a step ahead of my kids just now :)

@MrSmithsPhysicsonline 3 года назад

Thank you - this video in particular took a long time to put together. Still, I often use it with my own classes and it's nice to know that they're helping pupils all over. Are you a Teacher yourself? I could do with learning Python to help with some of the robotics projects I've done on my STEM channel.

@hyunmyunglee8962 2 года назад

Sir, what is the thing making the conduction that is taking place? The electrons that has jumped to the conduction band? Or the motion of wholes created in the valence band??

@MrSmithsPhysicsonline 2 года назад

Both are responsible for conduction in the semiconductor.

@TheCreepersAlive 4 года назад

in the course spec, it says some metals have partially filled valence bands and other metals have overlapping valence and conduction bands. it also says those with partially filled valence bands have higher conductivity than those with overlapping bands. how could this be if conduction requires electrons in the conduction band but the valence band isn’t even full?

@MrSmithsPhysicsonline 4 года назад

In order to conduct, a material must have free electrons within its conduction band or holes in its valence band.

@nellvincervantes6233 3 года назад

Why hole produce positive charge without changing the number of protons of silicon? Will it not violate conservation of charge? 🤔🤔

@MrSmithsPhysicsonline 3 года назад

The hole is just thought of as a positive charge, although it's actually the absence of an electron at that position in the crystalline lattice. The semiconductor is still electrically neutral.

@cosettea1986 6 лет назад

So if enough heat is given to a insulator, will it conduct?

@MrSmithsPhysicsonline 6 лет назад

I think I responded to this question before but I'd made a mistake in assuming you were talking about conduction of heat rather than electrical conduction. Insulating materials will increase in conductivity as temperature increases but, depending on the material, they may actually start to disintegrate before there is any noticeable change. It all depends on the material properties of the insulator and the band gap.

@nurr7162 5 лет назад

it is possible but since the energy will have to be so great it will damage the component

@vource2670 3 месяца назад

I think I’m just terrible at this lol

@MrSmithsPhysicsonline 3 месяца назад

Keep at it and you'll get better - find some past paper questions on the topic and read the marking scheme carefully. Also, watch the 3 semiconductors videos a second or third time - the points covered are straight from the questions that have been asked before and are most likely to come up again. Good luck!
