- The potential barrier in a semiconductor is because of a triple charge layer o a double charge layer O a single charge layer o the absence of any charge layersOptoelectronicsWhat is true about semiconductors? It is easy for electrons to move through them. O They are so rare that it's unusual to see them in daily life. It is hard for electrons to move through them. O You can change how easily electrons move through them.
