| 1. | The tunnel diode can also be used as a low-noise microwave amplifier.
|
| 2. | Tunnel diodes are also more resistant to ionizing radiation than other diodes.
|
| 3. | A lambda diode therefore cannot replace a tunnel diode directly.
|
| 4. | Lambda diodes work at higher voltage than tunnel diodes.
|
| 5. | It uses tunnel diodes, which utilize quantum mechanics theory, to amplify those very low signals.
|
| 6. | Examples are gas-discharge tubes, tunnel diodes, and Gunn diodes.
|
| 7. | The discontinuity caused by negative resistance devices ( such as tunnel diodes ) can also be seen.
|
| 8. | Tunnel diodes are usually made from germanium, but can also be made from gallium arsenide and silicon materials.
|
| 9. | Practical tunnel diodes operate at a few milliamperes and a few tenths of a volt, making them low-power devices.
|
| 10. | In the 1960s, Rochester continued to work at IBM, directing cutting edge research in cryogenics and tunnel diode circuits.
