The mechanisms of photoluminescence from silicon nano-crystals formed by pulsed-laser deposition in argon and oxygen ambient. The silicon core was then wrapped in felt and inserted into the eraser casing. It is, however, accepted that they will not be as powerful as silicon versions but the obvious advantages are apparent. The miniature tags contain silicon chips and antennas that transmit information to a receiver very much as the listening 'bugs' used by the security services. This is usually a silicon crystal which has been "doped": atoms of different atomic structure are implanted in the silicon to alter its electrical properties. The thickness of the silicon chip was 0.5 mm and the diameter of the active area was 2 mm. Supplemental silicon increases plasma and milk silicon concentrations in horses. The materials of interest are platinum, alumina and silicon monoxide. Provided a suitable potential is applied to the silicon, the electrons can be detected on an electrode. The neurochip has electrodes set inside small wells etched into the silicon. The silicon oxide layer insulates the two sides and stops any electrochemical charge transfer, which might damage the chip or the cell. The second tool, an inductively coupled plasma etcher, is used to produce microscopic mechanical components in silicon. The salt was mixed until uniformly wetted, and then colloidal silicon dioxide was added with continued mixing until a free flowing powder was obtained. The energy originally deposited in silicon is thus mainly converted into electron-hole pairs, which is the basis for photon detection. These examples are from corpora and from sources on the web.
