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
Long Term
Effects
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.
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.

METAL ORGANIC CHEMICAL VAPOR DEPOSITION
(MOCVD).
Advantages
How It Works
Creates compound
semiconductors
which are made of
more then one
element allowing
thing them to
process faster and
perform at higher
temps.
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).
