THREE ATOMS THICK SEMICONDUCTING FILM How It’s Made “Using a technique called metal organic chemical vapor deposition. Already used widely in industry, but with different materials, it starts with a powdery precursor, forms a gas and sprinkles single atoms onto a substrate, one layer at a time.” Practical Uses Can be used in a wide variety of devices to make them thinner and more flexible. Can be used to make thin high performance transistors. Long Term Effects Will allow circuitry to become smaller which enables smaller devices. Thinner laptops, monitors, TV, essentially anything that requires a circuit board. Drawbacks Since it’s a very new technology they are trying to figure out how to mass produce it and also see how it sticks to other surfaces. Picture of a three atoms thick semiconducting film

METAL ORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD). Advantages Creates compound semiconductors which are made of more then one element allowing thing them to process faster and perform at higher temps. How It Works Chemicals are vaporized and transported into a reactor with other gases. Chemical reactions occur which turns the chemical into the desired crystal (the compound semiconductor). Reactor
