• there are three types of materials. they are conductor , semi conductor and insulator.
• where the semi conductor lies between the other two. ie. controlled conduction is possible in semi conductor.
• thats why it is preferred in electronic devices.
• A PN junction is formed in all the three types of materials. but in semi consuctor the junction is very thin and easy to break it with the very low voltage.
