<p><b>New page</b></p><div>'''Semiconductor'''<br />
<br />
A '''[[Semiconductor]]''' is a material that has electrical conductivity between a [[conductor]] (such as metallic copper) and an [[insulator]] (such as glass). Semiconductors are the foundation of modern [[electronics]], including [[transistor]]s, [[solar cell]]s, [[light-emitting diodes]] (LEDs), and [[integrated circuit]]s. <br />
<br />
==Properties==<br />
<br />
Semiconductors differ from metals in their characteristic property of decreasing electrical [[resistivity]] with increasing temperature. The behavior can be understood in terms of the [[quantum states]] available to the [[electron]]s in the solid. <br />
<br />
==Types of Semiconductors==<br />
<br />
Semiconductors can be classified into two types: <br />
<br />
* '''[[Intrinsic semiconductor]]s''': These are pure semiconductors with no impurities. Silicon and germanium are examples of intrinsic semiconductors. <br />
<br />
* '''[[Extrinsic semiconductor]]s''': These are impure semiconductors. They are further classified into two types: N-type and P-type semiconductors.<br />
<br />
==Applications==<br />
<br />
Semiconductors have a wide range of applications. They are used in the manufacturing of various electronic devices, including transistors, diodes, and integrated circuits. They are also used in solar cells and light-emitting diodes.<br />
<br />
