👉 Undoped, also known as doped, is a term used in electronics and semiconductor engineering to describe an electronic component that has been intentionally left un-doped. This means that it has not been exposed to any external electric fields or currents, so there are no charges present on the surface of the component. In other words, the undoped component is a pure semiconductor material with no impurities or defects. Undoped components are often used in electronic circuits where the goal is to minimize interference from external
