Here, we are going to talk about energy band diagram of conductor, insulator and semiconductor. We will also think a little bit about the energy band. Solids may be insulators or conductors depending on the number of free electrons presents. All the solids can be classify into 3 types that is Conductor Insulator Semiconductor Read also … Read more
Here, we will consider about the types of electron emission. But before that we have to know the definition of electron emissions. Electron emission is state that the process of the liberation of free electrons from the metal surface of a substance is know as electron emission. Electron means negative charge particle and Emitting means producing. … Read more
Most semiconductor devices have one or more PN junction. PN junction are of great importance because they are actually the control elements for semiconductor devices. In – depth knowledge of the formation and properties of PN junction enables the reader to understand the operation of semiconductor devices. So let’s know a little more about PN … Read more
