Insulated metallic particles on the source electrode would constitute a porous floating gate. The particles would be charged or discharged by quantum mechanical tunneling during the application of writing or erasing voltages.
Integrated optical and microwave waveguides in electrooptical materials constitute a traveling wave electrooptical modulator in the configuration of a Mach-Zehnder interferometer.
Tunable submillimeter-wave generator would be a layered (Al/Ga)As device.
Measured current vs voltage curve of the contact deposited with the AlAs barrier indicates the presence of a Schottky barrier 0.85 V high. The straight current vs voltage line of a similar contact deposited without the AlAs barrier indicates that this contact is ohmic.
Typical fluorescence spectra of single-crystal fibers of the indicated materials. The fibers are doped with triply ionized titanium.
PBMR was developed to demonstrate technolgies that may be desirable in pushbroom radiometry and to demonstrate the push-broom concept in an airborne prototype.
Phase conjugator compares the phase
Automatic filling system transfers liquid helium from a storage vessel to an experimental apparatus under computer control. Gaseous helium from a cylinder supplies the pumping pressure.
Abrupt changes in the intensity of scattered light on each plot indicate the onset of formation of particles at the indicated power levels. The formation of particles can be prevented by keeping the power low.
