quantum well वाक्य

उदाहरण वाक्य

1. For the resonant excitation, the central energy of the laser corresponds to the lowest exciton resonance of the quantum well.
2. Thin metal films can also support quantum well states, in particular, metallic thin overlayers grown in metal and semiconductor surfaces.
3. The active layer of the Nichia devices was formed from InGaN quantum wells or quantum dots spontaneously formed via self-assembly.
4. The lighter isotope has a higher energy state in the quantum well and will thus be preferentially formed into products.
5. The medium where the amplification takes place, consists of stacks of thin layers of semiconductors that together form quantum wells.
6. Researchers at Princeton University have recently built a quantum well laser which is no bigger than a grain of rice.
7. When a heterojunction is formed by two different semiconductors, a quantum well can be fabricated due to difference in band structure.
8. Quantum wells transmit electrons of any energy above a certain level, while quantum dots pass only electrons of a specific energy.
9. They have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers.
10. This quantization of the energy levels of the electrons allows a quantum well laser to emit light more efficiently than conventional semiconductor lasers.
