Boron-Doped Silicon Wafers

Boron-doped silicon substrates are used as a base material in the fabrication of semiconductor devices, specifically as a p-type doping material in the creation of p-n junctions. These junctions are crucial in the functioning of various electronic devices such as solar cells, transistors, and diodes. The addition of boron impurities to silicon allows for control of electrical conductivity and the creation of p-type semiconductors.
