Schottky barrier

Ok, imagine you have two playgrounds next to each other, and there's a fence between them. Now, you want to go from one playground to the other, but you can't climb the fence or go through it. What do you do?

Well, the only way to get from one playground to the other is to find a special entrance. This entrance is called a Schottky Barrier. Just like the fence between the playgrounds, the Schottky Barrier is like a wall that blocks things from getting through. But if you know where the entrance is, you can get through it easily.

In real life, the Schottky Barrier is a special type of barrier that's made of metal. It's commonly used in electronics and semiconductors. The barrier stops electric charges from crossing over, but if you know where the gate is, you can get through it easily.

Think of the Schottky Barrier like a guard at a party. The guard only lets in certain people who know the password or are on the guest list. If you're not on the list or don't know the password, you can't get in. Similarly, the Schottky Barrier only lets in certain electric charges that know how to get through it.

So, in summary, the Schottky Barrier is like a gate that stops electric charges from passing through, but if you know where the gate is, you can get through it easily.
