The copper and aluminium are good examples of a conductor  \nA very poor conductor of electricity is termed as insulator. The glass, wood, mica, diamond are the examples of an insulator.  \nA metal having conductivity which is between conductor and an insulator is called semiconductor. The silicon and germanium are the examples of a  \nsemiconductor. This does not conduct current at low temperatures but as temperature increases these materials behave as good conductors..  \nENERGY BAND DIAGRAMS  \nCONDUCTORS  \nIn the metals like copper, aluminium there is no forbidden gap between valence band and conduction band. The two bands overlap.  \nHence even at room temperature, a large number of electrons are available for conduction.  \nSo without any additional energy, such metals contain a large number of free electrons and hence called good conductors.  \nINSULATORS  \nIn case of such insulating material, there exists a large forbidden gap in between the conduction band and the valence band.  \nPractically it is impossible for an electron to jump from the valence band to  \nthe conduction band. Hence such materials cannot conduct and called insulators.  \nThe forbidden gap is very wide, approximately of about 7 eV is present in insulators. For a diamond, which is an insulator, the forbidden gap is about 6 eV.  \nSuch materials may conduct only at very high temperatures or if they are subjected to high voltage. Such conduction is rare and is called breakdown of an insulator.  \nThe other insulating materials are glass, wood, mica, paper etc.  \nSEMICONDUCTORS  \nThe forbidden gap in such materials is very narrow as shown in Fig. Such materials are called semiconductors.  \nThe forbidden gap is about 1 eV.  \nIn such materials, the energy provided by the heat at room temperature is sufficient to lift the electrons from the valence band to the conduction band.  \nINTRINSIC SEMICONDUCTORS  \nA sample of semiconductor in its purest form is called an intrinsic semiconductor.  \nThe impurity content in intrinsic semiconductor is very small, of the order of one part in 100 million parts of semiconductor.  \nSource : [http://mediatoget.blogspot.in/2011/06/classification-of-materials](http://mediatoget.blogspot.in/2011/06/classification-of-materials)based-on.html","cbCainhlxNECq9Ti","https://ap.wps.com/l/cbCainhlxNECq9Ti","pdf",75313,"English","# Classification of Materials Based on Energy Band Theory\n## Energy Band Diagrams\n### Conductors\n### Insulators\n### Semiconductors\n### Intrinsic Semiconductors","[{\"question\":\"How does energy band theory classify materials?\",\"answer\":\"It classifies materials based on their ability to conduct current, dividing them into conductors, insulators, and semiconductors according to the structure of valence and conduction bands and the size of the forbidden gap.\"},{\"question\":\"Why do conductors conduct electricity easily at room temperature?\",\"answer\":\"In conductors, the valence and conduction bands overlap, so many electrons are already available for conduction without needing additional energy.\"},{\"question\":\"What makes insulators unable to conduct current under normal conditions?\",\"answer\":\"Insulators have a wide forbidden energy gap between the valence band and conduction band, making it practically impossible for electrons to jump between them, so conduction occurs only under extreme conditions like high temperature or high voltage.\"}]","Classification of Materials Based on Energy Band Theory | PDF"]
