A CCD is a thin layer of silicon divided into a multitude of small squares known as «picture elements», usually referred to in the shortened form of «pixels».

To do this you need a positively doped and negatively doped layers of silicon and for maximum efficiency you need very, very pure silicon... The reason you can't make silicon solar panel windows is you can't make silicon clear.

Ali Hajmiri, Bren professor in the Engineering department at Caltech and the chief investigator of the paper of the lensless camera describes the basic construction of the camera - they have created a thin single layer of silicon photonics that mimics the lens and a camera sensor, reducing thickness and the cost of digital cams.

Osburn says that a hafnium transistor would still need a thin layer of silicon dioxide at the bottom of the gate insulator to dissipate excess charges that would otherwise accumulate there and interfere with the device.

This enables creating qubits in thin layers of silicon using a very high purity silicon isotope, 28Si, which produces a crystalline quality comparable to thin films usually made of natural silicon.

That's because it takes so much heat to build a layer of silicon memory — about 1,000 degrees centigrade — that any attempt to do so would melt the logic below.

That's because the gas can be used to make several of the layers in a silicon photovoltaic — from the top of the cell where it is used to deposit a layer of silicon nitride that ensures that all sunlight is absorbed, to the bottom where it can be used to deposit another layer that helps reflect back any missed photons of sunlight, boosting the efficiency of the cell at converting light into electricity.
