Why hole produce positive charge without changing the number of protons of silicon? Will it not violate conservation of charge? 🤔🤔
@MrSmithsPhysicsonline3 жыл бұрын
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.

@TheCreepersAlive4 жыл бұрын
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?
@MrSmithsPhysicsonline4 жыл бұрын
In order to conduct, a material must have free electrons within its conduction band or holes in its valence band.

So if enough heat is given to a insulator, will it conduct?
@MrSmithsPhysicsonline6 жыл бұрын
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.
