Silicon is used in most semiconductors for computer and electronic components, as is it considered to be the best semiconductor material. A semiconductor diode is a device typically made up of a single p-n junction. A material is semiconductor when it behaves either as a conductor or as an insulator, depending on the electric field in which it is located. Random access allows the PC processor to access any part of the memory directly rather than having to proceed sequentially from a starting place. These semiconductors typically form in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron , aluminium , gallium , indium ) and from group 15 (old group V, nitrogen , phosphorus , arsenic , antimony , bismuth ).
