1. The process, called "photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

2. Called "photon enhanced thermionic emission," or PETE, the process promises to surpass the efficiency of existing photovoltaic and thermal conversion technologies.

3. The thermionic emission cooling employing hetero structure is a high efficient cooling method.

4. Accordingly, the I-V characteristics of N and P type DBRs due to three kinds of current mechanisms:the drift-diffusion, pure drift and thermionic emission currents, have been analyzed theoretically.

5. The liberation of electrons from a hot wire is called thermionic emission.

6. The electron source may emit electrons either via field emission or thermionic emission.

7. Finally, our simulation result shows that conventional SOI SBSD-MOSFET can effectively suppress thermionic emission leakage current, but it still can not suppress tunneling leakage current.

8. Emission spectroscopic techniques are employed to study the loss of thermionic emission material barium from the cathode of a T12 fluorescent lamp.
