2.The filtering effect could be amplified by placing the ferromagnet in a resonant tunnel diode.
3.THE SECOND TYPE of organic light emitter is the large-molecule light-emitting polymer, also known as the polymer light-emitting diode (PLED).
4.Conventional resonant tunnel diodes allow currents to flow at a specific voltage, one at which the electrons have an energy that is resonant with the tunneling barrier.
5.Higher oxygen concentrations, the presence of combustibles, and the narrowness of the surgical field during endolaryngeal diode laser surgery are risk factors for airway fires.
6.The project, being developed along with the Institute of Photonics at the University of Strathclyde, involves making microscopic holes in the surface of LEDs to increase the level of light they give off.

8.Furthermore, it was found that we could use the GaN/SiN double buffer to achieve more reliable nitride-based LEDs.
9.The version incorporating a ferromagnet would have a barrier with different resonant voltages for up and down spins.
10.A high-resolution video camera, along with an infrared camera for navigation, was placed in the front of the craft along with three light-emitting-diode arrays for fill lighting and two quartz halogen lamps for spotlighting.
