WebMay 31, 2024 · Why p-type semiconductor are called acceptor? Since holes will “accept” free electrons, a Group 3 impurity is also called an acceptor. … Because an acceptor donates excess holes, which are considered to be positively charged, a semiconductor that has been doped with an acceptor is called a p-type semiconductor; “p” stands for positive. WebJan 25, 2024 · P-type material contains negatively charged acceptor ions (immobile) and positively charged holes (free). Properties of N-type materials The N-type semiconductor material is doped with donor impurity atoms. N-type material has a high free electrons concentration The concentration of holes in N-type material is very low.
