A smectic liquid crystal composition containing component (AI), component (B) and/or component (C), expressed by the following formulas: ##STR1## wherein R.sup.1 represents an alkyl group of 1 to 9 carbon atoms, R.sup.2 represents an alkyl group of 1 to 9 carbon atoms, R.sup.3 represents an alkyl group of 1 to 18 carbon atoms, R.sup.4 represents an alkyl group of 1 to 18 carbon atoms, X represents H or F, R.sup.5 represents an alkyl group of 6 to 15 carbon atoms and R.sup.6 represents an alkyl group of 6 to 15 carbon atoms. Ferroelectric liquid crystal material having a negative dielectric anisotropy is applicable to display element utilizing AC-stabilizing effect and .tau.-Vmin. Further, as to the composition containing ##STR2## as an additional component, SA phase appears within a broad range; hence the composition can be made up into a ferroelectric liquid crystal composition having a good alignment.

    摘要: Provided is an element structure whereby it is possible to produce a silicon-germanium light-emitting element enclosing an injected carrier within a light-emitting region. Also provided is a method of manufacturing the structure. Between the light-emitting region and an electrode there is produced a narrow passage for the carrier, specifically, a one-dimensional or two-dimensional quantum confinement region. A band gap opens up in this section due to the quantum confinement, thereby forming an energy barrier for both electrons and positive holes, and affording an effect analogous to a double hetero structure in an ordinary Group III-V semiconductor laser. Because no chemical elements other than those used in ordinary silicon processes are employed, the element can be manufactured inexpensively, simply by controlling the shape of the element.
