Copper is a very widely used semiconductor. Copper wire is used in electromagnets and electric motors. In electromagnets, it is wound around a metal core with electricity flowing through it to magnetise the metal core. And the same basic principle applies to small electric motors, only, they are encased in a magnet so the opposite sides cause force it into a centrifugal motion.
What else can I help you with?
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are the different kinds of materials that can be used as semiconductors Compare their properties and give an argument for the material mostly used to manufacture semiconductor devices?
There are many kinds of materials which can be used but currently the element most used to make semiconductors is Silicon. Silicon is not a natural semiconductor so it has to be "doped" with very small amounts of other materials to make it have semiconducting properties. That's enough to say for now, unless someone else wants to just dump a complete answer here! To prepare a full answer to this obvious exam question you should do your own research on the Internet (Wikipedia perhaps?) and/or in technical libraries!
What kinds of materials would make good turbine blades?
Ideally, they should be constructed of light weight materials like reinforced aluminum
What kinds of materials would make good wind turbine blades?
Ideally, they should be constructed of light weight materials like reinforced aluminum
What are the five main groups of materials?
The five main groups of materials are metals, polymers, ceramics, composites, and semiconductors. Each group has unique properties and characteristics that make them suitable for different applications in various industries.
What element is used to make semiconductors?
silicon
Are there materials other than just silicon that are being used to make semiconductor or other solid state electronic devices?
The other materials other than just silicon used to make semiconductors and other solid state electronic devices are germanium and gallium arsenide.

Materials and resources used to make shoes?
the matirels are leather and different kinds of cussiond fabric
What kinds of materials do you use to make modern bridges?
toothpicks, hot glue, and fishing line
What kinds of materials are recycled to make compost?
vegetable peelings, grass and dead fruits and plants
Do compound semiconductors behave as intrinsic semiconductors?
No, compound semiconductors do not behave as intrinsic semiconductors because they have different band structures due to the combination of different elements. Compound semiconductors have unique electrical properties that make them suitable for specific applications that require different performance characteristics compared to intrinsic semiconductors.
