radiative recombination उदाहरण वाक्य

उदाहरण वाक्य

1. At some later time, the ejected charge returns to the nanocrystal ( restoring charge neutrality and therefore radiative recombination ).
2. These electrons then undergo a process of radiative recombination, during which electrons and positively charged " holes " recombine in the base.
3. It has been predicted theoretically that a'photonic'material environment can control the rate of radiative recombination of an embedded light source.
4. The decay of excitons yields a single-exponential decay function since the probability of their radiative recombination does not depend on the carrier density.
5. The colors are a result of the radiative recombination of electrons and ions and the relaxation of electrons in excited states back to lower energy states.
6. In crystalline silicon, even if there are no crystalline defects, there is still Auger recombination, which occurs much more often than radiative recombination.
7. Therefore, the Shockley-Queisser calculation takes radiative recombination into account; but it assumes ( optimistically ) that there is no other source of recombination.
8. Light emission from InGaN layers grown on such GaN buffers used in blue and green LEDs is expected to be attenuated because of non-radiative recombination at such defects.
9. However, if the excited electrons are prevented from reaching these recombination places, they have no choice but to eventually fall back into the valence band by radiative recombination.
10. Generally the process is described by a " radiative recombination constant ", C _ r, which is about 10  " 12 cubic centimeters per second.
