Well, seeing as tubes were used for amplification, AND for switching, before transistors were developed, and that transistors were developed as a means of miniaturizing electronics for things like ...

Think of the word “relay” and the image that might come to mind is of an old-fashioned telegraph system consisting of a series of magnetic switches that replicate-thereforerecreate and propagate a ...

A transistor fabricated from the crystalline phase of an organic semiconductor material could provide a path to improved switching speeds — rivalling those of devices built from inorganic materials ...
