A semiconductor is a material that has a particular property that can allow or block the flow of electrons - a property that is very useful in transistors, integrated circuits, and other electronic components (such as microprocessors).

∙ 8y agoSemiconductors, as the name suggests, can either conduct or act as an insulator. They are made of solid material, usually Silicon, but have been made using Germanium.
By putting them together in various Sandwiches, they can be formed into electronic devices that can be controlled, to conduct or not conduct, or conduct a little bit.
The simplest semiconductor is a diode, or rectifier. Using a slice of 'N' type and a slice of 'P' type substance. Current will only flow one way, blocking a reverse current.
Putting three slices together, sandwiching either a 'P' or 'N' type of material between others, creates a transistor. The flow of electrons across all three, can be controlled by varying the current through the middle slice.
Other devices can also be made using layers of different material, such as Diacs, Thyristors, FETs and complex circuits built on chips of silicon.
So you can see that 'semiconductors' include all devices used in modern electronics. Resistors and capacitors can also be made of semiconductor material, and included inside 'chips' of silicon, forming complete, stand alone, circuits.

metals, semimetals or nonmentals
Where are semimetals found?
They are surrounding the staircase line in the periodic table. But not all of them are semimetals. Boron(B), Silicon(Si), Germanium(Ge), Arsenic(As), Antimony(Sb) and Tellurium(Te) are semimetals. Aluminum(Al) and Polonium(Po) are metals. The remaining ones surrounding the staircase line are non-metals.
