Liquid-crystal twisted nematic structures can be made with twist angles other than the conventional 90 degrees . It is shown that theoretically the transmission of such a structure when placed between two polarizers aligned parallel and perpendicular

Most samples of GaAs show properties similar to those of germanium and silicon, but it is possible to prepare GaAs with a resistivity at room temperature greater than 106 ohm‐cm, and the electrical properties are then more like those of the wide ba

Experiments show that the use of the homeotropic or homogeneous states of a nematic liquid crystal influences its dynamic scattering properties. The fastest rise time for the onset of dynamic scattering when a voltage pulse is applied is obtained whe

One of the problems encountered when making matrix-addressed liquid crystal displays is the poor discrimination obtained. This arises because the optical effect used to form the display does not have an adequate `threshold' as a function of drive vol

A study of the light output/current characteristics of epitaxial and diffused, red-emitting, GaP electroluminescent diodes shows that the output saturates at an emission density which is essentially constant for all diodes, irrespective of their effi

As long ago as 1907 Round, while studying silicon carbide detectors, observed semiconductor electroluminescence. However, it was not until the 1960’s that useful devices became available. The laboratory devices of the 1960’s are a major semicondu
