		<description><![CDATA[We looked at pure or intrinsic semiconductors in the previous post on Analog Electronics.
We can however, change the electrical properties of the pure semiconductors by adding certain impurities to their structure, a process called doping.
When doping semiconductors of groups 3 &#38; 4, these impurities are usually elements of group 3(acceptors) or 5(donors).

This gives rise to [...]]]></description>

		<description><![CDATA[We&#8217;ve often heard of terms like the Silicon Valley &#38; the Silicon Economy. What do they really refer to?
All modern day electronics are build using a special class of materials called semiconductors. These materials have an electrical resistivity between a conductor &#38; an insulator.
They are the foundations of all electronics which are computerized(computers, ipods, etc) [...]]]></description>
