These scientists wanted to find a way to make computer chips that are smaller and can do more things. They used a special material called MoS(2) to make their chips. They made two layers of chips on top of each other, like a cake with two layers. In one layer, they made more than 10,000 tiny transistors, which are like the brains of a computer. In another layer, they made about 500 transistors. They also made a two-layer chip with 200 tiny transistors.

But that's not all! They also made a special circuit that can do different things like sensing and storing information. They think that their work will help make even better computer chips in the future that are very small, but can do lots of different things.
