Describe The Difference Between P-type And N-type Semiconductor Materials? |
|
Answer» When a small AMOUNT of trivalent impurity (such as boron, gallium, indium or aluminium) is ADDED to a pure semiconductor crystal during crystal growth, the resulting crystal is called a P-type semiconductor. When a small amount of PENTAVALENT impurity (such as ARSENIC, antimony, bismuth or PHOSPHORUS) is added to a pure semiconductor crystal during crystal growth, the resulting crystal is called the N-type semiconductor. When a small amount of trivalent impurity (such as boron, gallium, indium or aluminium) is added to a pure semiconductor crystal during crystal growth, the resulting crystal is called a P-type semiconductor. When a small amount of pentavalent impurity (such as arsenic, antimony, bismuth or phosphorus) is added to a pure semiconductor crystal during crystal growth, the resulting crystal is called the N-type semiconductor. |
