An LED is a semiconductor. It's an electronic device.

Now that same kind of software could destroy an oil refinery or a pharmaceutical factory or a semiconductor plant.

It's made not of a bulky tube, but of a thin layer of a semiconductor material that serves as the gamma detector.

Canada recently became a partner in a multinational cooperative endeavour to support research into semiconductor and oxide materials using the floating zone process.

The Crystal Growth of Solid Solution Semiconductors Experiment, using the Advanced Automated Directional Solidification Furnace on its first mission, successfully grew a crystal of mercury cadmium telluride alloy, a semiconductor, to study the physics of additive thermal and composition driven convection during crystal growth.
