    摘要: Compositions for use in non-linear optical devices. The compositions have high first molecular electronic hyperpolarizability (.beta.) and therefore display high second order non-linear optical properties when incorporated into non-linear optical devices. The acceptor and donor groups which are used in the compositions, along with the .pi.(pi)-bridge length is chosen to optimize second-order non-linear optical responses.

    摘要: This invention provides compositions of matter that contain an electron emitting substance and an expansion material. The expansion material may, for example, be an intercalation compound. When a film is formed from the composition, expansion of the expansion material typically causes rupturing or fracturing of the film. No further treatment of the surface of the film is typically required after expansion of the expansion material to obtain good emission properties. A surface formed from such a fractured film acts as an efficient electron field emitter and thus is useful in vacuum microelectronic devices.

    摘要: This invention provides a process for improving the field emission of an electron field emitter comprised of an acicular emitting substance such as acicular carbon, an acicular semiconductor, an acicular metal or a mixture thereof, comprising applying a force to the surface of the electron field emitter wherein the force results in the removal of a portion of the electron field emitter thereby forming a new surface of the electron field emitter.
