12. Class 12th Physics |Semiconductor & its Types | Generation & Recombination of e-h Pairs

let us discuss an important phenomena in semiconductors that is generation and recombination of electron hole pairs, as we have already discussed that , in a pure semiconductor , concentration of electrons is equal to concentration of holes. and we can write that , due to . thermal agitation. continuously , new electron hole pairs […]

4 Experiments with Batteries

Hey, what’s up guys? Thanks for joining us on The King of Random. Batteries are everywhere and we use them in all sorts of stuff, and a lot of the time they come with warnings saying to make sure you dispose of them properly, and how they can be dangerous if you misuse them. Well […]

What is Physics?

What is Physics?

What makes physics so cool? To me, physics is awesome and interesting because it asks the one question no other [physical] science does: “how?” Physics looks at how things happen-the reason things happen-and explains it. No other [physical] science does this. Chemistry deals with the result of things happening while biology deals with why things […]

How to Build a Teleporter with Aliens

Suppose we’re working with aliens who live near Alpha Centauri to build a wormhole teleporter so we can go visit them – for dinner, or interstellar diplomacy, or whatever. Of course we’ll need to be able to talk with them about what to make each side of the portal out of, how big to make […]

10. Class 12th Physics | Semiconductor & its Types | Types of Semiconductors | by Ashish Arora

let us study the types of semiconductors , semiconductors are categorized in two major categories on the basis of conductivity , we can write that , as discussed , conductivity , of semiconductors increases with, rise in temperature .we can also say that , this is an important point we must note it that , […]

7. Class 12th Physics | Semiconductor & its Types | Band Structure in Metals | by Ashish Arora

let us discuss about band structure in metals . as , we have already studied about conduction band . in earlier section , i just write it again. that conduction band is , the overlapped region , of common orbitals, of atoms, in a lattice structure , we know that all those electrons which exist […]

9. Class 12th Physics | Semiconductor & its Types | Band Structure in Semiconductors | Ashish Arora

let us study the band structure in semi conductors , we can write that , band structure. in semiconductors are, similar to insulators, which. we have already studied ,in previous sections, that in insulators conduction band exist high above . the fermi level in valence band, but here we can say band structure in semiconductors […]

Wide Bandgap Semiconductors

In an ever-changing world, one constant is emerging. Our dependence on smaller, faster and more efficient electronics. Semiconductors are the foundation of modern electronics. But as current technology reaches its limits, where do we go next? The answer: Advance a technology we already have. Wide Bandgap Semiconductors operate at temperatures over 300 degrees, handle 10 […]

25. Physics | Magnetic field | Ampere’s Law | by Ashish Arora (GA)

dear students , now we are going to discuss another important law, in magnetic field calculation that is ampere’s law, like , we have studied in electrostatics . we have studied that in electrostatics. Goss law. is easier , in calculation . of electric field for symmetric charge distributions. because we have studied that in […]
