Applied Nanotech Inc. (ANI) has announced the introduction of two new proprietary products based on nanotechnology - carbon nanotube gated electron sources (triode structures) and colloidal solutions of silicon nanocrystals (quantum dots).
The carbon nanotube gated electron sources are the first commercially available electron sources based on carbon nanotubes with an integrated gate to modulate the electron emission characteristics with voltages of approximately 400 volts. ANI currently supplies diode mode (without gate) electron sources for applications like such as x-ray spectrometers and miniature x-ray tubes. The new triode mode structures will lower the control voltages to less than 100 volts, reducing costs and extending the life of the devices.
The latest development in silicon-based materials are silicon nanocrystals (quantum dots). A "quantum confinement" physical effect makes the silicon particles become smaller (in the range of 1 nanometer to 4 nanometers) and enables the use of silicon in visible light optoelectronics. This means that the market silicon now extends to the imaging industry, biotechnology, visible nanoLEDs (light emitting diodes) and nanolasers.
