Intrinsic semiconductors are pure, stoichiometric materials that have not been doped with additional compounds in order to modify their electrical conductivity. The band gap of these materials increases as we move from group IV materials like silicon and germanium to III-V (GaAs etc) and I

Semiconductors 1: intrinsic & extrinsic semiconductors (Higher Physics)
Higher Physics - first in a series of 3 videos on semiconductors. This video covers intrinsic semiconductors, band theory and doping to form n-type or p-type semiconductors. ----------------------------------------------------- Support the channel – you can buy me a coffee here... http
From playlist Higher - Electricity
Rather than just relying on intrinsic electrons in polls it is possible doped semiconductors with electronic donors and acceptors. These provide the ability to dope and material to be either n-type or p-type. We show this with examples of phosphorus and boron doping into the silicon lattic

What are Conductors and Insulators? | Don't Memorise
There are lots of ways to categorise different materials based on their Physical or Chemical Properties. One way is to categorise them based on their CONDUCTIVITY! Based on this property, we classify materials as Conductors, Insulators and Semiconductors. In this video, we will study abou

Temperature and dopant dependence of electrical conductivity in semiconductors
Metals become less conductive as they are heated due to atomic vibrations increasing. The thermal vibrations also increase and affect the mobility of carriers in semiconductors, but at the same time there is exponential increase in the number of carriers being promoted across the band gap.
