Transcript of Semiconductors
elements compare, and contrast? How do semiconductors react to other elements Why are semiconductors important? A gas is a state of matter that doesn't have a defined shape or volume. GASES DO NOT CONDUCT ELECTRICITY. partially conductive solid: a solid material
that has electrical conductivity between that of a
conductor and an insulator. The arrow points towards the
semiconductors on the periodic table. Why use semi conductors rather than regular conductors? Semi-Conductors 1. Semiconductors are used for making electronic devices.
2. Semiconductors are also used to fabricate cells and absorb light.
3. Semiconductors Because only semiconductors are capable of selectively conducting current, and can be made such that they manipulate the electricity in certain directions. Semiconductors also allow us to make computers tiny, as opposed to taking up an entire room. Similarities: all semiconductors partially conduct electricity and are metals Differences: All semiconductors have different amounts of protons and electrons, or else they would be the same element. Semiconductors react to heat, by changing it to electricity. After the doping process, even a small amount of heat can be transferred into electricity. Metal- a chemical element that is malleable and ductile, usually solid, has a characteristic luster, and is a good conductor of heat and electricity, e.g. copper or iron
