Quantum wells have a range of applications due to their unique properties:
1. Lasers: Quantum wells are employed in the active regions of semiconductor lasers to improve performance by providing higher gain and lower threshold currents. 2. Detectors: They are used in infrared photodetectors and other sensors due to their tunable bandgap. 3. High Electron Mobility Transistors (HEMTs): Quantum wells enhance the electron mobility in these transistors, making them suitable for high-frequency applications.
