A P - type semiconductor can be obtained by adding - Toppr Ask?
WebA p-type semiconductor is formed by adding a III group element (such as B, Al) as a doping element. An impurity added creates a vacancy of electrons. For example in the above picture, The impurity atom is surrounded by four silicon atoms. It provides the atoms to make only three covalent bonds as it has only three valence electrons. WebDiodes are the simplest devices that can be made with semiconductors. In diodes, current is able to flow in one direction but not the other. This device is formed when a P-type and an N-type semiconductor are put together. The combination of these semiconductors does not itself conduct electricity. address of elizabeth seton school WebTwo of the most important materials silicon can be doped with, are boron (3 valence electrons = 3-valent) and phosphorus (5 valence electrons = 5-valent).
