(a)
Interpretation:
Whether nitrogen-doped diamond is n -type or p -type semiconductor should be classified.
Concept introduction:
Semiconductors are devices that have conductivity intermediate between conductors and insulators and their conductivity gets enhances when doped.
Doped semiconductors are used in commercialized electronic devices as diodes, transistors, LEDs, photovoltaic cells. They all differ in their functions which are as follows:
- Diodes convert alternating current to direct current.
- Photovoltaic cells convert sunlight to electricity.
- LEDs act as a light source.
- Transistors amplify an electrical signal in an integrated circuit.
(b)
Interpretation:
The MO diagram comparing the pure diamond with doped diamond should be drawn.
