Gallium Nitride (GaN)
Gallium Nitride (GaN) is a wide bandgap semiconductor that has various applications in electronics and optoelectronics. Let's analyze the given statements:
Statement 1- It is a very hard, mechanically stable wide bandgap semiconductor.
This statement is correct. GaN has a very high melting point (over 2500°C) and is mechanically stable due to its strong covalent bonds. It is also a wide bandgap semiconductor (3.4 eV), which means it requires a higher voltage to conduct electricity, making it an ideal material for high-power electronic devices.
Statement 2- Gallium nitride crystals can be grown on a variety of substrates, including sapphire, silicon carbide (SiC) and silicon (Si).
This statement is also correct. GaN crystals can be grown on various substrates, including sapphire, SiC, and Si, using techniques such as metal-organic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE). This flexibility in substrate choice allows for the integration of GaN-based devices with existing electronic systems.
Therefore, both statements 1 and 2 are correct.
